Currently this test fails on 2 situations:
1) The scratch device supports trim/discard. In this case any modern
version of mkfs.btrfs outputs a message (to stderr) informing that
a trim is performed, which the golden output doesn't expect:
btrfs/017 - output mismatch (see /git/xfstests/results//btrfs/017.out.bad)

(Run 'diff -u tests/btrfs/017.out /git/xfstests/results//btrfs/017.out.bad' to see the entire diff)
So like others tests do, just redirect mkfs' standard error.
2) On platforms with a page size greater than 4Kb. At the moment btrfs
doesn't support a node/leaf size smaller than the page size, but it
supports a larger one. So use the max supported node size (64Kb) so
that the test runs on any platform currently supported by Linux.
