To check is btrfs-convert create bad filesystem with
leaf across stripes.
It is happened in progs version <=v4.1.2, and fixed by patch titled:
btrfs: convert: Avoid allocating metadata extent crossing stripe boundary
which was merged in v4.2.
Notice thar this testcase can not report error in old version of
btrfs-progs, because "btrfs check" can't check this type of error
in those version, but we have another testcase in fsck-tests, to
check is "btrfs check" support this check.
So, the above 2 testcase together can check leaf-crossing-stripes
bug in all versions.
