scsi: ufs: mcq: Fix missing argument 'hba' in MCQ_OPR_OFFSET_n
[ Upstream commit 2fc39848952dfb91a9233563cc1444669b8e79c3 ]
The MCQ_OPR_OFFSET_n macro takes 'hba' in the caller context without
receiving 'hba' instance as an argument. To prevent potential bugs in
future use cases, add an argument 'hba'.
