btrfs: block-group: refactor how we delete one block group item

Browse source

When deleting a block group item, it's pretty straight forward, just
delete the item pointed by the key.  However it will not be that
straight-forward for incoming skinny block group item.

So refactor the block group item deletion into a new function,
remove_block_group_item(), also to make the already lengthy
btrfs_remove_block_group() a little shorter.
