Subject: [PATCH] ufs: mcq: Fix missing argument 'hba' in MCQ_OPR_OFFSET_n

The MCQ_OPR_OFFSET_n macro has taken 'hba' on the caller context
without receiving 'hba' instance as an argument.  To prevent potential
bugs in future use cases, this patch added an argument 'hba'.

Fixes: 2468da61ea09 ("scsi: ufs: core: mcq: Configure operation and runtime interface")
