Sometimes on fast enough test vm, btrfs/028 fails like:
btrfs/028 31s ... - output mismatch (see /home/adam/xfstests-dev/results//btrfs/028.out.bad)

QA output created by 028
+/home/adam/xfstests-dev/tests/btrfs/028: line 64: kill: (2459) - No such process
Silence is golden
...
It's caused by killing already finished process.
There is no need for kill command to pollute the golden output, so
just redirect all of its stdout and stderr to null.
