libfuse: have passthrough_hp return an error with invalid mount options

generic/003 fails currently because if you specify -o relatime we will
fail to mount, but not return an error, so the test thinks that we
support relatime and then hilarity ensues.  Set ret so that if we get
any failures while trying to mount we will properly error out.
