qcacld-3.0: Add presence check for structure tDot11fQosMapConfigure

qcacld-2.0 to qcacld-3.0 propagation

Current logic use the "not present" structure tDot11fQosMapConfigure
to calculate the array index which lead to the array overflow and
crash of VosMCThread. Add check code to avoid this problem.
