rpc: fix dispatch for node device APIs for virt drivers

Despite their names, the following APIs:

    virNodeDeviceDettach
    virNodeDeviceDetachFlags
    virNodeDeviceReAttach
    virNodeDeviceReset

are all handled by the virt drivers, not the node device driver.
A bug in the RPC generator meant that these APIs were sent to
the nodedev driver for handling. This caused breakage with the
split daemons, since nothing was available to process them.
