Mark Johnston 06459adc89 Fix a race in pmap_emulate_modified().
pmap_emulate_modify() was assuming that no changes to the pmap could
take place between the TLB signaling the fault and
pmap_emulate_modify()'s acquisition of the pmap lock, but that's clearly
not even true in the uniprocessor case, nevermind the SMP case.
