Commit 66b8304f removed the rte_intr_enable() call from
i40evf_dev_interrupt_handler() as a "bonus". On one of my systems this causes
the AdminQ messages to stop beeing delivered to the VF. This results in
unability to initialize and use the port. With this patch it works again.

System in question:
Wind River OVP6 running kernel 3.10.58-ovp-rt58-WR6.0.0.13_preempt-rt
