[PATCH] xfstests: remove check_scratch_fs in btrfs/012

[Liu Bo <bo.li.liu@oracle.com>]

From: Liu Bo <liub.liubo@gmail.com>

btrfs/012 is a case to verify btrfs-convert feature, it converts an ext4 to
btrfs firstly and do something, then rolls back to ext4.

So at last we have a ext4 on the scratch device, but setting _require_scratch
will force a btrfsck on a ext4 fs because $FSTYP here is btrfs, and it ends up
with a failure report of _check_btrfs_filesystem.

Now that we have deliberately check the final ext4 fs in btrfs/012, just do not
set _require_scratch in this case.
