cperciva d34b4913e6 Add xenpic_dynirq_disable_intr and set it as the .pic_disable_intr method ... for xenpic_dynirq_template. This fixes a panic when a virtual disk is removed, since that results in an interrupt channel being disabled and NULL isn't very good function for disabling interrupts. We should probably have a xenpic_pirq_disable_intr as well; I'm not adding that here because (a) I'm not sure what uses pirqs so I don't have a test case, and (b) the xenpic_pirq_enable_intr code is significantly more complex than the xenpic_dynirq_enable_intr code, so I'm not sure what should go into a xenpic_pirq_disable_intr routine.
