scsi: ufs: core: Revert "WB is only available on LUN #0 to #7"
Ccommit d3d9c4570285 ("scsi: ufs: Fix memory corruption by
ufshcd_read_desc_param()") has properly fixed stack overflow issue.
As a result, commit a2fca52ee640 ("scsi: ufs: WB is only available on LUN
#0 to #7") is no longer required. Revert it.
