rtlwifi: Add TX report and disable key to force wait until report acked.
When using EAPOL to do a PTK rekey, there is a possible race condition.
When msg 3/4 is received, the supplicant will send msg 4/4 and install
the new key immediately; however, the driver must make sure that msg 4/4
is sent before installing the new key. We use TX report to ensure it is
sent.
