btrfs: Verify that every chunk has corresponding block group at mount time
If a crafted image has missing block group items, it could cause
unexpected behavior and breaks the assumption of 1:1 chunk<->block group
mapping.
Although we have the block group -> chunk mapping check, we still need
chunk -> block group mapping check.
This patch will do extra check to ensure each chunk has its
corresponding block group.
