From: Andrei Otcheretianski <andrei.otcheretianski@xxxxxxxxx>
If the driver requires external SAE authentication, it would result in
registration for all authentication frames, so even non SAE auth frames
might be forwarded to user space instead of being handled internally.
Fix this by using more strict match pattern, limiting the registration
to the SAE authentication algorithm only.
