Al Viro bedf03d0b8 path_openat(): fix double fput() ...

commit f15133df08 upstream.

path_openat() jumps to the wrong place after do_tmpfile() - it has
already done path_cleanup() (as part of path_lookupat() called by
do_tmpfile()), so doing that again can lead to double fput().

[ luis: backported to 3.16:
  - adjusted context as 3.16 doesn't have path_cleanup() helper,
    introduced by 893b7775a7 ("fs/namei.c: new helper (path_cleanup())") ]
