In a virtualized environment it is possible for a loading driver to discover
that Firmware is already loaded to the device, and that this FW does not match
its own. This can happen for example if different Physical Functions are
Assigned to different VMs in which different driver versions are loaded. The
code in this patch ensures that only drivers with matching FW are loaded over
the device, and that in the case described above where the Firmware version
doesn't match the driver load is aborted.
