io_uring/cmd: return -EOPNOTSUPP if net is disabled
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.
