drm/xe/pf: Don't advertise support to enable VFs if not ready
Even if we have not enabled SR-IOV support using the platform
specific has_sriov flag, the hardware may still report SR-IOV
capability and the PCI layer may wrongly advertise driver support
to enable VFs. Explicitly reset the number of supported VFs to
zero to avoid confusion.
Applications may read the /sys/bus/pci/devices/.../sriov_totalvfs
prior to enabling VFs using the sriov_numvfs to check if such an
operation is possible.
