qcacld-3.0: Call correct PMO API for setting PS params

WMI_STA_PS_PARAM_INACTIVITY_TIME and
WMI_STA_PS_PARAM_MAX_RESET_ITO_COUNT_ON_TIM_NO_TXRX
need to be sent as WMI_STA_POWERSAVE_PARAM_CMDID param IDs.
Thus use pmo_tgt_send_vdev_sta_ps_param instead of
pmo_tgt_vdev_update_param_req in appropriate locations.
