qcacld-3.0: SME: Remove obsolete support for Class B stats

SME currently has legacy code to support the tCsrGlobalClassBStatsInfo
data structure. However these stats were specific to the WDI firmware
API used by older generations of hardware, and this interface is not
supported by WMI. In addition the support for these stats has been
removed from HDD.  So remove support for these stats from SME.
