Further reduce the use of Giant by vm_fault(): Giant is held only when
manipulating a vnode, e.g., calling vput(). This reduces contention for
Giant during many copy-on-write faults, resulting in some additional
speedup on SMPs.
Note: debug_mpsafevm must be enabled for this optimization to take effect.
