  Log:
   - We no longer have to bother with PDIRUNLOCK, lookup() handles it for us.
   - Network filesystems are written with a special idiom that checks the
     cache first, and may even unlock dvp before discovering that a network
     round-trip is required to resolve the name.  I believe dvp is prevented
     from being recycled even in the forced unmount case by the shared lock
     on the mount point.  If not, this code should grow checks for VI_DOOMED
     after it relocks dvp or it will access NULL v_data fields.
