cperciva 005e768447 Adjust the critical section protecting _xen_flush_queue to cover the
entire range where the page mapping request queue needs to be atomically
examined and modified.

Oddly, while this doesn't seem to affect the overall rate of panics
(running 'make index' on EC2 t1.micro instances, there are 0.6 +/- 0.1
panics per hour, both before and after this change), it eliminates
vm_fault from panic backtraces, leaving only backtraces going through
vmspace_fork.
