PCI: Fix use of uninitialized MPS value
If "pcie_bus_config == PCIE_BUS_PERFORMANCE", we don't initialize "smpss", so we pass a pointer to garbage into pcie_bus_configure_set(), where we compute "mps" based on the garbage. We then pass the garbage "mps" to pcie_write_mps(), which ignores it in the PCIE_BUS_PERFORMANCE case. Coverity isn't smart enough to deduce that we ignore the garbage (it's a lot to expect from a human, too), so initialize "smpss" to a safe value in all cases. Found by Coverity (CID 146454).
