Protect io_uring_cmd_sock() to be called if CONFIG_NET is not set. If
network is not enabled, but io_uring is, then we want to return
-EOPNOTSUPP for any possible socket operation.
This is helpful because io_uring_cmd_sock() can now call functions that
only exits if CONFIG_NET is enabled without having #ifdef CONFIG_NET
inside the function itself.
