Subject: [PATCH] net/virtio: fix Rx interrupt setup

[ upstream commit e7b9d1d2806c6bb8f30922c3cd6736b3076b7ec2 ]

When use rte_eth_dev_configure() to enable rx queue interrupt for virtio
devices, virtio_init_device() isn't called to set up the interrupt
environment, which causes rx queue interrupt setup failed. This patch is
to fix this issue.

Fixes: 26b683b4f7d0 ("net/virtio: setup Rx queue interrupts")
