qcacmn: Fix compilation error when WLAN_SUPPORT_GREEN_AP is disabled

Problem & Solution: WLAN_SUPPORT_GREEN_AP is enabled by default.
cfg_green_ap_params.h file gets included only when this flag is enabled.
So, in case of setting WLAN_SUPPORT_GREEN_AP=0, this file need not be
included to avoid compilation errors.
