eCryptfs: Filename encryption only supports password auth tokens
Returns -ENOTSUPP when attempting to use filename encryption with
something other than a password authentication token, such as a private
token from openssl. Using filename encryption with a userspace eCryptfs
key module is a future goal. Until then, this patch handles the
situation a little better than simply using a BUG_ON().
