Can Guo 04c116e2bd scsi: ufs: core: Let the sq_lock protect sq_tail_slot access 
When accessing sq_tail_slot without protection from sq_lock, a race
condition can cause multiple SQEs to be copied to duplicate SQE slots. This
can lead to multiple stability issues. Fix this by moving the *dest
initialization in ufshcd_send_command() back under protection from the
sq_lock.
