Stall workaround doesn't work with bcm4320a devices like with bcm4320b.
This workaround actually causes more stalls/device freeze on bcm4320a.
Therefore disable stall workaround by default.

rndis_query_oid overwrites *len which stores buffer size to return full size
of received command and then uses *len with memcpy to fill buffer with
command.

Ofcourse memcpy should be done before replacing buffer size.

rndis_wlan didn't know about NL80211_AUTHTYPE_AUTOMATIC and simple

v2: use NDIS_80211_AUTH_AUTO_SWITCH instead of _OPEN.
    This will make device try shared key auth first, then open.
