Revision 1.99 of this file changed the allocation request from
VM_ALLOC_INTERRUPT to VM_ALLOC_SYSTEM. There was no mention of
this in commit log as it was considered harmless. Guess what:
it does harm. WITNESS showed that we can not safely grab the
page queue lock in vm_page_alloc() in all cases as we may have
to sleep on it. Revert the request to VM_ALLOC_INTERRUPT to
circumvent this. We panic if vm_page_alloc returns 0. I'm not
entirely happy about this, but we have bigger fish to fry.
