If we discover a bad BLOCK_GROUP_ITEM_KEY with offset = 0, we'll end up looping

next block group starting at the current object + the offset. If offset is 0,

btrfs-progs: check: do early check for read_tree_block
Although we have enhanced read_tree_block() from a lot of different
aspects, it lacks the early bytenr/blocksize alignment check.
And the lack of such check can lead to strange use-after-free bugs, due
to the fact that alloc_extent_buffer() will free overlapping extent
buffers, and allocate new eb for the usage.
So we should not allow invalid bytenr/blocksize even passed to
btrfs_find_create_tree_block().
This patch will add such check so we won't trigger use-after-free bug
then.

btrfs-progs: Do extra chunk check before processing chunk item
Current we only do chunk validation check at mount time.
It's good for most case, but for fuzzed or manually crafted images, we
can insert a CHUNK_ITEM key into root tree.
Since mount time check will only check chunk tree, it will not check
CHUNK_ITEM in root tree.
Even with previous key type check against leaf owner, it is still
possible to modify the leaf owner to by-pass it.
So we still need to check chunk validation before processing it.
