Expose pci_sriov_get_totalvfs() to Rust PCI drivers so they can query how many SR-IOV VFs a device supports. Use a conditional C helper because the !CONFIG_PCI_IOV version of pci_sriov_get_totalvfs() is a static inline function and is therefore not emitted into the Rust bindings. Return Option<NonZero<u16>> so Rust callers must handle the zero value that represents unavailable SR-IOV.
