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
