igb_uio: fix build with kernel <= 3.17

igb_uio: fix build with kernel <= 3.17

Compile fails when kernel version is <= 3.17 with error:
"dereferencing pointer to incomplete type". This is because struct
uio_device definition is not exposed in kernel earlier than 3.17.

This patch fixes it by using pointer of rte_uio_pci_dev as
dev_id instead of uio_device for irq device handler.
