icjx: disable interrupts in interrupt worker

Browse source 
Interrupts have to be disabled if interrupt worker processes them,
otherwise assertion may occur as another interrupt tries to queue
worker that is not available (because it processes previous interrupts).
Interrupts are re-enabled after the worker leaves the loop processing
previous interrupts.
