If the v_type is going to change when loading the NFS attribute cache,
purge the vnode from the namecache first. This prevents cache_purge()
from later getting confused and trying to cache_zap() a namecache entry
multiple times over, due to cache_zap() believing that the entry does not
need to be removed from the vnode destinations queue.
