btrfs: extent-tree: Use btrfs_ref to refactor btrfs_inc_extent_ref()
Use the new btrfs_ref structure and replace parameter list to clean up the usage of owner and level to distinguish the extent types. Signed-off-by: Qu Wenruo <wqu@suse.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
