nl80211: Use separate flag for 4-way handshake offload 

Commit d896874f86 ("nl80211: Indicate 802.1X 4-way handshake offload
in connect") used the req_key_mgmt_offload flag to indicate to the
driver that it should offload the 802.1X handshake. However, this field
was existing and used for a different offload API. This causes
wpa_supplicant to send a connect request without the WANT_1X_HS flag and
the subsequent set-pmk is rejected causing the connection to fail. Fix
that by introducing a new flag req_handshake_offload so the offloads are
no longer entangled.
