[PATCH net-next] tg3: Set real_num_rx_queues for non-multiq devs

Commit 2ddaad3 entitled "tg3: Use
netif_set_real_num_{rx,tx}_queues()" added a new call to
netif_set_real_num_rx_queues in tg3_enable_msix().  This call also needs
to be added to the legacy path to correctly reflect the actual number of
rx queues.
