The NFSv4 protocol doesn't use the Mount protocol, so it doesn't make sense to add an entry for an NFSv4 mount to /var/db/mounttab. Also, r308871 modified umount so that it doesn't remove any entry created by mount_nfs. Reported on freebsd-current@. Reported by: clbuisson@orange.fr MFC after: 2 weeks
