Faicker Mo b84c5632c7 net: net_failover: Fix the deadlock in slave register 
There is netdev_lock_ops() before the NETDEV_REGISTER notifier
in register_netdevice(), so use the non-locking functions
in net_failover_slave_register().
failover_slave_register() in failover_existing_slave_register() adds lock
and unlock ops too.

Call Trace:
