scsi: ufs: core: Fix error handler host_sem issue
Fix the issue where host_sem is not released due to a new return path in
commit f966e02ae521 ("scsi: ufs: core: Fix runtime suspend error
deadlock").
Check pm_op_in_progress before acquiring hba->host_sem to prevent
deadlocks and ensure proper resource management during error
handling. Add comment for use ufshcd_rpm_get_noresume() to safely
perform link recovery without interfering with ongoing PM operations.
