drivers: usb: Stop transfers on MSG_HALT 



Some of the versions of windows XP send MSG_HALT
without sending RNDIS_OID_GEN_CURRENT_PACKET_FILTER
before. This causes the interface to lose IP upon consequent
enable.
With this fix we close the transfer with the IPA correctly, and
allowing the next connect to open the connection correctly.
