[PATCH v2 2/3] btrfs/053: fix test failure when running with btrfs-progs v6.0+

[fdmanana@kernel.org]

From: Filipe Manana <fdmanana@suse.com>

In btrfs-progs v6.0 the --leafsize (-l) command line option was removed
from mkfs.btrfs, so btrfs/053 can fail with v6.0+ in case the scratch
device does not have a btrfs filesystem created before running the test,
in which case mounting the scratch device fails.

The change was introduced by the following btrfs-progs commit:

  f7a768d62498 ("btrfs-progs: mkfs: remove support for option --leafsize")

Change the test to use --nodesize (-n) instead, since it exists in both
old and new btrfs-progs versions. Also redirect mkfs output to the test's
log file and fail explicitly if mkfs failed.
