Amos Kong bbfa18fca4 qdev: fix get_fw_dev_path to support to add nothing to fw_dev_path
Recent virtio refactoring in QEMU made virtio-bus become the parent bus
of scsi-bus, and virtio-bus doesn't have get_fw_dev_path implementation,
typename will be added to fw_dev_path by default, the new fw_dev_path
could not be identified by seabios. It causes that bootindex parameter
of scsi device doesn't work.

This patch implements get_fw_dev_path() in BusClass, it will be called
if bus doesn't implement the method, tyename will be added to
fw_dev_path. If the implemented method returns NULL, nothing will be
added to fw_dev_path.

It also implements virtio_bus_get_fw_dev_path() to return NULL. Then
QEMU will still pass original style of fw_dev_path to seabios.

v2: only add nothing to fw_dev_path when get_fw_dev_path() is
    implemented and returns NULL. then it will not effect other devices
    don't have get_fw_dev_path() implementation.
v3: implement default get_fw_dev_path() in BusClass
