failover: should_be_hidden() should take a bool

Browse source 
We didn't use at all the -1 value, and we don't really care.  It was
only used for the cases when this is not the device that we are
searching for.  And in that case we should not hide the device.

Once there, simplify virtio-Snet_primary_should_be_hidden.
