[Gabriel L. Somlo]

Using "-kenel <file>" results in a segmentation fault (at least with
qemu-system-x86_64). Bisect says the breakage was introduced by commit

    qdev: support to get a device firmware path directly
    
    commit 6b1566c (qdev: Introduce FWPathProvider interface) did a
    good job for supproting to get firmware path on some different
    architectures.
    
    Moreover further more, we can use the interface to get firmware
    path name for a device which isn't attached a specific bus,
    such as virtio-bus, scsi-bus etc.
    
    When the device (such as vhost-scsi) realize the TYPE_FW_PATH_PROVIDER
    interface, we should introduce a new function to get the correct firmware
    path name for it.

Reverting the commit seems to fix the problem for me, as a temporary
solution.
