eapol: relax (but warn) on secure bit check in handshake 1/4

Hostapd commit bc36991791 now properly sets the secure bit on
message 1/4. This was addressed in an earlier IWD commit but
neglected to allow for backwards compatibility. The check is
fatal which now breaks earlier hostapd version (older than 2.10).

Instead warn on this condition rather than reject the rekey.
