qcacld-3.0: WMA: Remove obsolete support for tCsrPerStaStatsInfo

WMA currently has legacy code to support the tCsrPerStaStatsInfo 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 WMA.
