Xiao Wang 20c0a0c4e8 net/fm10k: initialize link status in device start 
Fm10k host driver can't manage PHY directly and provides a fake link
status by always reporting LINK_UP. We should initialize link status
in device start, otherwise application will get LINK_DOWN status
when LSC configured.

Fixes: 9ae6068c86 ("fm10k: add dev start/stop")
