Konstantin Belousov a7163bb962 Eliminate some vm object relocks in vm fault. 
For the vm_fault_prefault() call from vm_fault_soft_fast(), extend the
scope of the object rlock to avoid re-taking it inside
vm_fault_prefault(). It causes pmap_enter_quick() sometimes called
with shadow object lock as well as the page lock, but this looks
innocent.
