[RFC 1/3] driver_nl80211: check 4-way handshake offload support

[Andrei Otcheretianski]

From: Eliad Peller <eliad at wizery.com>

Set the WPA_DRIVER_FLAGS_4WAY_HANDSHAKE flag if the
driver indicates both 4-way handshake PSK and 1X support.
Currently wpa_supplicant doesn't distinguish between 4-way
handshake for 1x and PSK, but nl80211 API has different
capabilities for each one (at least according to latest discussions).
