vhost_net_device_ops is internal implementation in vhost lib.
register_cuse_device will be vhost driver register API. There is no need for it

eal: make the comment more accurate
eal: set kdrv to RTE_KDRV_NONE if kernel driver isn't managing the device.
eal: use new RTE_ARCH_X86 macro for x86 arch
eal: simple code rework
eal: map IO port only when kernel driv
positive return of devinit of pci driver means the driver doesn't support

For all other IO port mapping errors, return -1.
Note than if VFIO/UIO fails, now we don't fall back to port IO.

Performance boost could be observed if the virtio backend isn't the bottleneck
or in VM2VM
case.
There are also several vhost optimization patches to be submitted later.
