Series scsi: ufs: Use pre-calculated offsets in ufshcd_init_lrb | expand

Commit Message

Avri Altman Sept. 9, 2024, 9:56 a.m. UTC 
Replace manual offset calculations for response_upiu and prd_table in
ufshcd_init_lrb() with pre-calculated offsets already stored in the
utp_transfer_req_desc structure. The pre-calculated offsets are set
differently in ufshcd_host_memory_configure() based on the
UFSHCD_QUIRK_PRDT_BYTE_GRAN quirk, ensuring correct alignment and
access.
