Subject: [PATCH] fix #1405: sort pci ids by functions

QemuServer::lspci() iterates over /sys/bus/pci/devices which
doesn't guarantee any order which means functions sometimes
ended up in the wrong order and it was never clear which
one would get the additional options such as x-vga passed
to them.
