CVE: NA

------------------------------------------------------------------

In probe_vendor_drivers, all registered vendor drivers are traversed.
This is not a good idea. If a vendor driver is not implemented well
enough, it may cause the system to panic. Use the vendor id and
device id to select a proper driver.

In the pervious device registration logic, since the live migration
operation ops of the three accelerator devices is the same.
Therefore, only one driver entity will be registered. As a result,
only the first sec will be loaded successfully, while hpre and zip
cannot be loaded.

The acc live migration driver needs to be adapted.
