It does this so we can try and dirty the inode quickly without having to deal with the ENOSPC problems. But if it does get back ENOSPC it handles it properly. The problem is use_block_rsv does a WARN_ON whenever this case happens, even tho btrfs_dirty_inode takes it into account and actually expects to get -ENOSPC if things are particularly tight. So instead just remove the warning.
