bonding: check return value of register_netdevice() in bond_newlink() 

Very similar to commit 544f287b84
("bonding: check error value of register_netdevice() immediately"),
we should immediately check the return value of register_netdevice()
before doing anything else.

Fixes: 005db31d5f ("bonding: set carrier off for devices created through netlink")
