The device on auxiliary bus doesn't support being probed again
without being removed firstly. The PMD will detect and return error
for this unsupported operation. Some of the resources would be
cleared wrongly. When quitting, there will be unexpected error like
crash.
To prevent this, the device driver will be checked before probing a
device.
