scsi: ufs: core: Change MCQ interrupt enable flow

Move the MCQ interrupt enable process to
ufshcd_mcq_make_queues_operational() to ensure that interrupts are set
correctly when making queues operational, similar to
ufshcd_make_hba_operational(). This change addresses the issue where
ufshcd_mcq_make_queues_operational() was not fully operational due to
missing interrupt enablement.

This change only affects host drivers that call
ufshcd_mcq_make_queues_operational(), i.e. ufs-mediatek.
