[PATCH 36/36] random: convert to ->poll_mask

The big change is that random_read_wait and random_write_wait are merged into a single waitqueue that uses keyed wakeups. Because wait_event_* doesn't know about that this will lead to occassional spurious wakeups in _random_read and add_hwgenerator_randomness, but wait_event_* is designed to
