crypto: qat - fix linking errors when PCI_IOV is disabled

Browse Source 
When CONFIG_PCI_IOV=n, the build of the QAT vfio pci variant driver
fails reporting the following linking errors:

    ERROR: modpost: "qat_vfmig_open" [drivers/vfio/pci/qat/qat_vfio_pci.ko] undefined!

    WARNING: modpost: suppressed 1 unresolved symbol warnings because there were too many)

Make live migration helpers provided by QAT PF driver always available
even if CONFIG_PCI_IOV is not selected. This does not cause any side
effect.
