[PATCH] USB: rndis updates (mostly cleanup)
Some bugfixes and lots of cleanup (net code shrink):
- On reset, force the RNDIS state machine its initial state
- Hook up the RNDIS (outgoing) filters to the CDC mechanism
- Lots of cleanup:
* Eliminate duplicate copy of OID table;
* Unify handlying of the OID "query" response data pointer;
* Reduce code duplication for calculating query response lengths;
* Remove some checks for "can't happen" errors;
* Get rid of debugging #ifdefs by making the debug flag an integer level
Most of the patch, by volume, relates to those query response cleanups.
It incidentally shaves off a few hundred bytes of object code.
