From: Su Yue <Damenly_Su@xxxxxxx>
while excluding super stripes from one block group, the logical bytenr
should not be excluded if the block group's start + length equals the
bytenr since the bytenr is not belong to the block group.
This is insipred by same bugous code of btrfs-progs.
The fuzz image is rejected to be mounted by tree-checker, but not
bad to enhance the check in practice.
