 - Consistently track ni_dvp and ni_vp with dvfslocked and vfslocked rather
   than trying to optimize it into a single lock.  This adds more calls to
   lock giant with non smpsafe filesystems but is the only way to reliably
   hold the correct lock.
 - Remove an invalid assert in the mountedhere case in lookup and fix the
   code to properly deal with the scenario.  We can actually have a lookup
   that returns dp == dvp with mountedhere set with certain unmount races.
