qcacld-3.0: Remove legacy ImplicitQosIsEnabled remnants

Change I0c6354960b49d680e3efe304ea3300059c37015c ("qcacld-3.0: ADD
MLME INI items of WMM Configuration") relocated some WMM config items
to MLME. However this change left behind in HDD the documentation and
CFG macros for ImplicitQosIsEnabled, so remove these remnants.
