user_statfs(): import pathname only once
Convert the user_path_at() call inside a retry loop into getname_flags() +
filename_lookup() + putname() and leave only filename_lookup() inside
the loop.
In this case we never pass LOOKUP_EMPTY, so getname_flags() is equivalent
to plain getname().
The things could be further simplified by use of cleanup.h stuff, but
let's not clutter the patch with that.
