i40evf: ignore link up if not running

Browse source

[ Upstream commit e0346f9fcb ]

If we receive the link status message from PF with link up before queues
are actually enabled, it will trigger a TX hang.  This fixes the issue
by ignoring a link up message if the VF state is not yet in RUNNING
state.
