qemu-ga: make get-fsinfo work over pci bridges
Iterate over the PCI bridges to lookup the PCI device associated with the block device. This allows to lookup the driver under the following syspath: /sys/devices/pci0000:00/0000:00:02.2/0000:03:00.0/virtio2/block/vda/vda3 It also works with an "old-style" Q35 libvirt hierarchy: root complex -> DMI-PCI bridge -> PCI-PCI bridge -> virtio controller, ex: /sys/devices/pci0000:00/0000:00:03.0/0000:01:01.0/0000:02:01.0/virtio1/block/vda/vda3 The setup can be reproduced with the following qemu command line (Thanks Marcel for help): qemu-system-x86_64 -M q35 \ -device i82801b11-bridge,id=dmi2pci_bridge,bus=pcie.0 -device pci-bridge,id=pci_bridge,bus=dmi2pci_bridge,addr=0x1,chassis_nr=1 -device virtio-blk-pci,scsi=off,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1,bus=pci_bridge,addr=0x1 For consistency with other syspath-related debug messages, replace a \"%s\" in the message with '%s'.
