Add support for cfg80211 set_pmksa/del_pmksa/flush_pmksa. Updating PMKID
entry list is done on driver side since NDIS API requires full list update.

v2:
 - fixed to use new netdev_dbg/warn/etc instead of old devdbg/warn/etc
 - fixed false padding from struct ndis_80211_bssid_info

rndis_query_oid() uses full output buffer size to copy response buffer
from rndis_command()/device. This doesn't cause problems as response buffer
is sized based on output buffer but does copy extra unset bytes.
So change rndis_query_oid() so that only meaningful bytes are being copied.

Also in case of malfunctioning device/cable/etc returned data offset from
device might be wrong so bound check memory access correctly, so add
checks for this.

These macros are too similar to the dev_<level> equivalents
but take a usbnet * argument.  Convert them to the recently
introduced netdev_<level> macros and remove the old macros.

The old macros had "\n" appended to the format string.
Add the "\n" to the converted uses.

Some existing uses of the dev<foo> macros in cdc_eem.c
probably mistakenly had trailing "\n".  No "\n" added there.

Fix net1080 this/other log message inversion.

rndis_wlan didn't know about NL80211_AUTHTYPE_AUTOMATIC and simple

    This will make device try shared key auth first, then open.
