scsi: ufs: host: mediatek: Fix unbalanced IRQ enable issue

[ Upstream commit 91cad911edd1612ed28f5cfb2d4c53a8824951a5 ]

Resolve the issue of unbalanced IRQ enablement by setting the
'is_mcq_intr_enabled' flag after the first successful IRQ enablement.
Ensure proper tracking of the IRQ state and prevent potential mismatches
in IRQ handling.
