Subject: checkpatch: fix git "fatal" warning if file argument outside kernel tree

commit bcf4271d4bc3 ("checkpatch: allow not using -f with files that are
in git") in linux-next causes checkpatch to emit a fatal message:

fatal: <file>: '<file>' is outside repository at '<kernel_dir>'

Fix that by sending git's error output to /dev/null instead.
