stash: drop superfluos pathspec parameter

Since 833622a ("stash push: avoid printing errors", 2018-03-19) we
don't use the 'git clean' call for the pathspec case anymore.  The
commit however forgot to remove the pathspec argument to the call.
Remove the superfluos argument to make the code a little more obvious.
