The ufshcd_scsi_block_requests() and ufshcd_scsi_unblock_requests()
calls were introduced in ufshcd_exception_event_handler() to prevent
that querying the exception event information would time out. Commit
10fe5888a40e ("scsi: ufs: increase the scsi query response timeout")
increased the timeout for querying exception information from 30 ms to
1.5 s and thereby eliminated the risk that a timeout would happen.
Hence, the calls to block and unblock SCSI requests are superfluous.
Remove these calls.
