btrfs-progs: avoid looping forever when a bad blockgroup key is found
If we discover a bad BLOCK_GROUP_ITEM_KEY with offset = 0, we'll end up looping
forever when we read the block groups in. This is due to the search for the
next block group starting at the current object + the offset. If offset is 0,
we'll just get the same key over and over and never advance. This patch
ensures that we'll advance at least one objectid per iteration.
