Set EPT bits of guest pages in pmap_enter instead of doing it
after an uvm_fault: uvm_fault maps in neighboring pages of
the faulting page. We want EPT bits set for those as soon as
possible as well. This avoids additional EPT violations
causing further uvm_faults when the guest accesses the
neighboring pages.
