Subject: [PATCH] Btrfs: cleanup to make the function
 btrfs_delalloc_reserve_metadata more logic

The original code is a little confusing and not clear, The right
way to deal with the kernel code like this:
		[...]
		if (ret)
			goto out;
		[...]

So i move the common clean_up code to the place labeled with
out_fail, this will be easier to maintain.
