scsi: ufs: Add compatibility with 3.1 UFS unit descriptor length

Browse source

For UFS 3.1, the normal unit descriptor is 10 bytes larger than the RPMB
unit. However, both descriptors share the same desc_idn, to cover both unit
descriptors with one length, we choose the normal unit descriptor length by
desc_index.
