The quota_tree was set up to use the empty_block_rsv before which would be problematic when the filesystem is filled up and ENOSPC happens during internal operations while the quota tree is updated and COWed (when the btrfs_qgroup_info_item items) are written. In fact, use_block_rsv() which is used in btrfs_cow_block() falls back to the global_block_rsv in this case. But just in order to make it more clear what is happening, change it to explicitly use the global_block_rsv.
