btrfs: Remove unused op_key var from add_delayed_refs
Added as part of 86d5f9944252 ("btrfs: convert prelimary reference tracking to use rbtrees") but never used. tmp_op_key essentially subsumed that variable. Signed-off-by: Nikolay Borisov <nborisov@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
