[ Upstream commit 6cb7f0b8c9b0d6a35682335fea88bd26f089306f ]
We already have the extent buffer's level in an argument, there's no need to first ensure the extent buffer's data is loaded (by calling btrfs_read_extent_buffer()) and then call btrfs_header_level() to check the level. So use the level argument and do the check before calling btrfs_read_extent_buffer().
