Hmm, I don't know. To put both the nd and path is at the moment only used in
some error paths. I have another series of patches pending which is using
path_put_conditional outside of error paths. So please don't remove
it. Besides that the naming completely hides that the conditional release of
the vfsmount reference. Besides that I would name it path_put_both() just to
make it more "beautiful" wrt the other path_put*() functions.

IMHO introducing another label just to use it here isn't worth the change.
