igb: fix VF init without setup

In case of multi-process application, the secondary process can initialize
the driver without configuring queues. In this case the Rx/Tx functions
were not initialized because it was only done in queue setup.

Fix by reproducing the same behaviour as in eth_igb_dev_init().
