path_openat(): fix double fput()r11.1_msm8916q10.0_msm8916
[ Upstream commit f15133df088ecadd141ea1907f2c96df67c729f0 ]
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().
