Ensure that VF provisioning and eudebug enabling is exclusive by
returning EPERM on attempt enable one of those features while the
other is already enabled. Check that enable_eudebug sysfs entry is
not present when the driver is loaded in VF mode.

Since eudebug KMD side is still in upstream review phase, the related
kernel side change can be found here:
