USB: gadget: rndis conformance tweak

Support OID_802_3_MAC_OPTIONS in gen_ndis_query_resp() of rndis.c to
make RNDIS gadget pass 1c_SetMulticast subtest in Microsoft NDISTest6:

  http://www.microsoft.com/whdc/DevTools/tools/NDIStest.mspx

The other tests in NDISTest6 are passed.

[ dbrownell@users.sourceforge.net: remove OID_802_3_MAXIMUM_LIST_SIZE
setting ... it was bogus, this code only handles one entry, not 32.
And we don't know what would break if we lied about that... ]
