nic_uio: fix device binding at boot

When loading nic_uio from /boot/loader.conf as specified in the Getting
Started Guide doc, the NIC devices were not bound at boot. Unloading the
nic_uio driver and reloading it would cause them to be bound, however.

The root cause appears to be the fact that when the module is loaded at
boot, the call to find the pci device when parsing the b:d:f parameter
fails to return the device. That means that later on when the device
is probed as part of a PCI scan, no action is taken as it's not recorded
as a device to be used.

We fix this by having the b:d:f string parsed again on probe if the
initial check to see if it's an already-known device fails. In my tests,
this causes the NIC devices to be successfully bound at boot time, as
well as leaving things working as before in the case the module is loaded
post-boot.

igb_uio: map dummy DMA forcing IOMMU domain attachment

For using a DPDK app when iommu is enabled, it requires to
add iommu=pt to the kernel command line. But using igb_uio driver
makes DMAR errors because the device has not an IOMMU domain.

Since kernel 3.15, iommu=pt requires to use the internal kernel
DMA API for attaching the device to the IOMMU 1:1 mapping, aka
si_domain. Previous versions did attach the device to that
domain when intel iommu notifier was called.

This is not a problem if the driver does later some call to the
DMA API because the mapping can be done then. But DPDK apps do
not use that DMA API at all.
