d6b2a38a92 modules/mqnic: Fix link status monitoring, initialize stored link status on start to "down" 
Assume that the hardware link status is "down" when a netdev is brought "up"
administratively ("ip link set dev ... up"). This way a change of link status is
always occuring, in case hardware link status is indeed still "up" at that point
in time.

Otherwise bringing a netdev administratively "down" and "up" again, while the
hardware was "up" before and stays "up" during the administrative "down" period,
results in no netif_carrier_on() being called, because struct
mqnic_priv::link_status does not change.
