Tegra194: memctrl: fix bug in client order id reg value generation 

Client order id reset values are incorrectly and'ed with
mc_client_order_id macro, which resulted in getting reg value as
always zero. Updated mc_client_order_id macro to avoid and'ing outside
the macro, to take the reg value and update specific bit field
as necessary.
