Re: [PATCH] btrfs: Remove never reached code

[David Sterba <dsterba@suse.cz>]

The subject is too generic, and the changelog could say something about
the btrfs_panic semantics. Otherwise the change is ok, previously there
was just BUG_ON, then if -> btrfs_panic and after moving the kfree after
the print, the return has been added, but this is just redundant.
