The following change set introduces HAVE_VFIO_DEV_REQ_INTERFACE
and used in the below files.

drivers/bus/pci/linux/pci_vfio.c
drivers/bus/pci/pci_common.c
lib/librte_eal/linuxapp/eal/eal_interrupts.c

However, Except the first file, the change missed to include
<rte_vfio.h> where HAVE_VFIO_DEV_REQ_INTERFACE defined.
This creates runtime following error on vfio-pci mode and
kernel >= 4.0.0 combination.

EAL: [rte_intr_enable] Unknown handle type of fd 95
EAL: [pci_vfio_enable_notifier]Fail to enable req notifier.
EAL: Fail to unregister req notifier handler.
EAL: Error setting up notifier!
EAL: Requested device 0000:07:00.1 cannot be used

Fixes: cda94419964f ("vfio: fix build with Linux < 4.0")
