net, lib/once: remove {net_}get_random_once_wait macro
DO_ONCE(func, ...) will call func with spinlock which acquired by spin_lock_irqsave in __do_once_start. But the get_random_once_wait will sleep in get_random_bytes_wait -> wait_for_random_bytes. Fortunately, there is no place to use {net_}get_random_once_wait, so we could remove them simply.
