accel/ivpu: Move parts of MMU event IRQ handling to thread handler

To prevent looping infinitely in MMU event handler we stop
generating new events by removing 'R' (record) bit from context
descriptor, but to ensure this change has effect KMD has to perform
configuration invalidation followed by sync command.

Because of that move parts of the interrupt handler that can take longer
to a thread not to block in interrupt handler for too long.
This includes:
 * disabling event queue for the time KMD updates MMU event queue consumer
   to ensure proper synchronization between MMU and KMD

 * removal of 'R' (record) bit from context descriptor to ensure no more
   faults are recorded until that context is destroyed
