rust: pci: add sriov_get_totalvfs() helper
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.
