s390/qeth: clean up setting of BLKT defaults
When called from qeth_core_probe_device(), qeth_determine_capabilities()
initializes the device's BLKT defaults. From all other callers, the
ccw_device has already been set online and the BLKT setting is skipped.
Clean this up by extracting the BLKT setting into a separate helper that
gets called from the right place.
