bus/pci: fix devargs on probing again

As per the comments in this code section, since there is a matching device,
it is now its responsibility to manage the devargs we've just inserted.
But the matching device ptr's devargs is still uninitialized or not pointing
to the newest dev_args that were passed as a parameter to local_dev_probe().
This is needed particularly in the case when *probe is called again* on an
already probed device as part of adding a representor port to OVS-DPDK.
