Remove the if clause in usb_write_port_complete and process the urb
status regardless of bSurpriseRemoved, bDriverStopped and
bWritePortCancel.

The only possible results of urb status processing are updates to
bSurpriseRemoved and bDriverStopped. All of the three status variable are
set to true only if the whole USB processing has to be stopped (when the
driver is unloaded or when the system goes to sleep).

It's no problem if one of the "stop everything" variables is already set
and the urb status processing sets another one.

This patch removes the last goto in usb_write_port_complete. It's also
part of the ongoing effort to limit the use of the "stop everything"
variables.

-EINVAL to report the error in most cases, -ENOMEM for out-of-memory
errors and -EHOSTDOWN for service shutdown.

This patch acts as intermediatory to address the TODO item:
    * Get rid of custom function return values
for vc04_services/interface.

Merge tag 'fixes-2023-01-14' of git://git./linux/kernel/git/rppt/memblock

Pull memblock fix from Mike Rapoport:
 "memblock: always release pages to the buddy allocator in
  memblock_free_late()

  If CONFIG_DEFERRED_STRUCT_PAGE_INIT is enabled, memblock_free_pages()
  only releases pages to the buddy allocator if they are not in the
  deferred range. This is correct for free pages (as defined by
  for_each_free_mem_pfn_range_in_zone()) because free pages in the
  deferred range will be initialized and released as part of the
  deferred init process.

  memblock_free_pages() is called by memblock_free_late(), which is used
  to free reserved ranges after memblock_free_all() has run. All pages
  in reserved ranges have been initialized at that point, and
  accordingly, those pages are not touched by the deferred init process.

  This means that currently, if the pages that memblock_free_late()
  intends to release are in the deferred range, they will never be
  released to the buddy allocator. They will forever be reserved.

  In addition, memblock_free_pages() calls kmsan_memblock_free_pages(),
  which is also correct for free pages but is not correct for reserved
  pages. KMSAN metadata for reserved pages is initialized by
  kmsan_init_shadow(), which runs shortly before memblock_free_all().

  For both of these reasons, memblock_free_pages() should only be called
  for free pages, and memblock_free_late() should call
  __free_pages_core() directly instead.

  One case where this issue can occur in the wild is EFI boot on x86_64.
  The x86 EFI code reserves all EFI boot services memory ranges via
  memblock_reserve() and frees them later via memblock_free_late()
  (efi_reserve_boot_services() and efi_free_boot_services(),
  respectively).

  If any of those ranges happens to fall within the deferred init range,
  the pages will not be released and that memory will be unavailable.

  For example, on an Amazon EC2 t3.micro VM (1 GB) booting via EFI:
