Btrfs: only exclude supers in the range of our block group
If we fail to load block groups halfway through we can leave extent_state's on
the excluded tree. This is because we just lookup the supers and add them to
the excluded tree regardless of which block group we are looking at currently.
This is a problem because we remove the excluded extents for the range of the
block group only, so if we don't ever load a block group for one of the excluded
extents we won't ever free it. This fixes the problem by only adding excluded
extents if it falls in the block group range we care about. With this patch
we're no longer leaking space when we fail to read all of the block groups.
Thanks,
