net/netvsc: fix probe when VF not found

Browse Source 
It is possible that the VF device exists but DPDK doesn't know
about it. This could happen if device was blacklisted or more
likely the necessary device (Mellanox) was not part of the DPDK
configuration.

In either case, the right thing to do is just keep working
but only with the slower para-virtual device.
