[PATCH v2 1/2] sae: check return on sae_send_commit()

If this fails, in some cases, -EAGAIN would be returned up to netdev
which would then assume a retry would be done automatically. This
would not in fact happen since it was an internal SAE failure which
would result in the connect method return to never get sent.

Now if sae_send_commit() fails, return -EPROTO which will cause
netdev to fail the connection.
