Two ifnet misuse fixes for if_nve:

Browse Source 
(1) Don't manually configure if_output(), ether_ifattach() will do that
    for us as part of link-layer setup.

(2) Call if_detach() before stopping nve in order to prevent calls into
    the device driver after the driver has started shutting down.
