firewire: cdev: use atomic_t for iso_resource_auto todo member

The transition state of an iso_resource_auto client resource has no
effect on the client, so the client-level lock is not suitable for
protecting it.

At present, this state is the only member that requires mutual
exclusion. Adding a separate lock for it would be excessive.

Change the type of the transition state to atomic_t and use an atomic
compare-and-swap operation to preserve consistency.
