scsi: ufs: core: Fix MCQ tag calculation

The transfer command descriptor is allocated in ufshcd_memory_alloc() and
referenced by the transfer request descriptor with stride size
sizeof_utp_transfer_cmd_desc() instead of sizeof(struct
utp_transfer_cmd_desc).

Consequently, computing tag by address offset should also refer to the
same stride.
