scsi: ufs: mcq: Use ufshcd_mcq_poll_cqe_lock() in MCQ mode
In preparation for adding MCQ error handler support, update the MCQ code to
use the ufshcd_mcq_poll_cqe_lock() in interrupt context instead of using
ufshcd_mcq_poll_cqe_nolock(). This is to keep synchronization between MCQ
interrupt and error handler contexts because both need to access the MCQ
hardware in separate contexts.
