Use the helper function where it is open coded to increment the block_group reference count 'bg_count' so that it is less confusing while reviewing the code. As btrfs_get_block_group() is a one-liner we could have open-coded it, but its partner function btrfs_put_block_group() isn't one-liner which does the free part in it.
