scsi: ufs: core: Fix runtime suspend error deadlock

Browse source

Resolve the deadlock issue during runtime suspend when an error triggers
the error handler. Prevent the deadlock by checking pm_op_in_progress
and performing a quick recovery.  This approach ensures that the error
handler does not wait indefinitely for runtime PM to resume, allowing
runtime suspend to proceed smoothly.
