qcacld-3.0: Don't check MIC fail if SA is self MAC

When DUT connects to specific AP, it receives the frame whose
SA is self MAC and MIC failure flag is set at the same time.
This will cause disconnection with the AP because MIC failure.

To fix this unexpected disconnection issue, do not check MIC
failure if discard flag is set by fw.
