btrfs: use label to deduplicate error path at btrfs_force_cow_block()

Browse source

At btrfs_force_cow_block() we have several error paths that need to
unlock the "cow" extent buffer, drop the reference on it and then return
an error. This is a bit verbose so add a label where we perform these
tasks and make the error paths jump to that label.
