Note: The locking in this code is utterly broken. We should not be using the VM page queue mutex to protect the queue of pending Xen page mapping hypervisor calls. Even if it made sense to do so, this commit and r204160 introduce LORs between the vm page queue mutex and PMAP2mutex. (However, a possible deadlock is better than a guaranteed panic, and this change will hopefully make life easier for whoever fixes the Xen pmap locking in the future.)

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.
