KFD currently relies on MEC FW to clear tcp watch control
register by sending MAP_PROCESS packet with 0 of field
tcp_watch_cntl to HWS, but if the queue is suspended, the
packet will not be sent and the previous value will be
left on the register, that will affect the following apps.
So the solution is to clear the register as gfx v9 in KFD.
