wifi: nl80211: don't give key data to userspace

[ Upstream commit a7e57930 ]

When a key is requested by userspace, there's really no need
to include the key data, the sequence counter is really what
userspace needs in this case. The fact that it's included is
just a historic quirk.

Remove the key data.
