DESCRIPTION: This function is a wrapper for the power server's powerSrv_ReservePS function
INPUT: - hMacServices - handle to the Mac services object.
- psMode - Power save/Active request
- sendNullDataOnExit -
- powerSaveCBObject - handle to the Callback function module.
- powerSaveCompleteCB - Callback function - for success/faild notification.
OUTPUT:
RETURN: TI_STATUS - TI_OK / PENDING / TI_NOK.
