btrfs-progs: lowmem check: Fix false alert on missing chunk or dev extent

When checking chunk or dev extent, lowmem mode uses chunk length as dev
extent length, and if they mismatch, report missing chunk or dev extent
like:
------
ERROR: chunk[256 4324327424) stripe 0 did not find the related dev extent
ERROR: chunk[256 4324327424) stripe 1 did not find the related dev extent
ERROR: chunk[256 4324327424) stripe 2 did not find the related dev extent
------

However, only for Single/DUP/RAID1 profiles chunk length is the same as
dev extent length.
For other profiles, this will cause tons of false alert.

Fix it by using correct stripe length when checking chunk and dev extent
items.

This fixes the mkfs test failure when using lowmem mode check.

btrfs-progs: lowmem check: Fix false alert about file extent interrupt

As Qu mentioned in this thread
(https://www.spinics.net/lists/linux-btrfs/msg64469.html), compression
can cause regular extent to co-exist with an inlined extent. This
coexistence makes things confusing. Since it is currently allowed and
can appear in a filesystem, fix btrfsck to prevent a bunch of error
reports to appear that will make user feel uneasy.

When checking a file extent, record the extent_end of the regular extent
to check if there is a gap between the regular extents. Normally there
is only one inlined extent, so the extent_end of inlined extent is
useless. However, if a regular extent can co-exist with an inlined
extent, the extent_end of the inlined extent also needs to be recorded.
