[NET]: Missing proto_list_lock initialization.
The new protocol registration locking uses a rwlock to limit access
to the protocol list. Unfortunately, the initialisation:
static rwlock_t proto_list_lock;
Only works to initialise the lock as unlocked on platforms whose unlock
signal is all zeros. On other platforms, they think it's already locked
and hang forever.
