scsi: ufs: core: Reduce the size of struct ufshcd_lrb
The size of the data structures that are used in the hot path matters
for performance (IOPS). Hence this patch that reduces the size of struct
ufshcd_lrb on 64-bit systems by 16 bytes. The size of this data
structure is reduced from 152 to 136 bytes.
