qcacld-3.0: Clear mac_ctx->sap.sapCtxList for SAP if SSR happen

Browse source 
While SSR happen, hdd_reset_all_adapters will not clear
mac_ctx->sap.sapCtxList[sapctx->sessionId].pSapContext, and later the
sapctx will assign new sessionId after SSR restart SAP and update to
mac_ctx->sap.sapCtxList. So sapctx/old sessionId still can be
referenced by like wlan_sap_is_pre_cac_active and call pre cac cleanup
on unexpected port.

When SAP restart and set global sapCtxList in sap_set_session_param(),
find matched sapctx and clear it before assigning updated value.
