qcacmn: add utf event exception handler for invalid pdev_id

For the case in DBS, the psoc and pdev is one-to-one mapping,
but firmware will send per pdev_id information to host according
to the radio being tested, add a backup query to SOC_ID if the
pdev_id passed along from utf_event is invalid/unsupported to
work around this case.
