Subject: [PATCH v2] scsi: ufs: Remove an unpaired ufshcd_scsi_unblock_requests() in err_handler()
Commit 5586dd8ea250 ("scsi: ufs: Fix a race condition between error handler
and runtime PM ops") moves the ufshcd_scsi_block_requests() inside
err_handler(), but forgets to remove the ufshcd_scsi_unblock_requests() in
the early return path. Correct the coding mistake.
