scsi: ufs: core: Expand MCQ queue slot to DeviceQueueDepth + 1
The UFSHCI 4.0 specification mandates that there should always be at least
one empty slot in each queue for distinguishing between full and empty
states. Enlarge 'hwq->max_entries' to 'DeviceQueueDepth + 1' to allow
UFSHCI 4.0 controllers to fully utilize MCQ queue slots.
