Ungating the clock asynchronously causes ufshcd_queuecommand() to return SCSI_MLQUEUE_HOST_BUSY and hence causes commands to be requeued. This is suboptimal. Allow ufshcd_queuecommand() to sleep such that clock ungating does not trigger command requeuing. Remove the ufshcd_scsi_block_requests() and ufshcd_scsi_unblock_requests() calls because these are no longer needed. The flush_work(&hba->clk_gating.ungate_work) call is sufficient to make the SCSI core wait for clock ungating to complete.
