When echo a number to /sys/bus/pci/devices/xxx/sriov_numvfs to enable the
VF devices. A crash log occurred. This found to be access the IOV devices
config space failure issue.

The read/write config space from host would judge the pcie device plugin
or not by(Designware platform as example):

if (bus->primary == pp->root_bus_nr && dev > 0)
    return 0;

Although all PCIe devices for dev(coming from the device and function
number) is zero. But the dev is not zero for VF devices. So remove the
condition.

These PCI hosts were changed: designware, altera, xilinx.
