[PATCH] iseries_veth: Don't send packets to LPARs which aren't up

Hi Andrew, Jeff,

The iseries_veth driver has a logic bug which means it will erroneously
send packets to LPARs for which we don't have a connection.

This usually isn't a big problem because the Hypervisor call fails
gracefully and we return, but if packets are TX'ed during the negotiation
of the connection bad things might happen.

Regardless, the right thing is to bail early if we know there's no
connection.
