osmo_io: Avoid implementing non-existant situations

Both of our back-ends have a register_fd and unregister_fd back-end.

Let's simplify the code by not treating them as optional, which
introduces code paths that we never take, adds small runtime overhead
and makes the code harder to follow.

Should we ever introduce more backends which might not need those
call-backs, we can either have empty functions or think about how to
make them optional.
