[TG3]: Fix 5704 single-port mode
If the dual-port 5704 is configured as a single-port device with only one PCI function, it would trigger a BUG() condition in tg3_find_5704_peer(). This fixes the problem by returning its own pdev if the peer cannot be found. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
