s390/qeth: streamline control code for promisc mode
We have logic to determine the desired promisc mode in _each_ code path.
Change things around so that there is a clean split between
(a) high-level code that selects the new mode, and (b) implementations
of the various mechanisms to program this mode.
This also keeps qeth_promisc_to_bridge() from polluting the debug logs
on each RX modeset.
