Fix potential nvdrv submission race
The syncpoint maximum value represents the maximum possible syncpt value at a given time, however due to PBs being submitted before max was incremented, for a brief moment of time this is not the case which could lead to crashes or other such behaviour if a game waits on the fence at the right moment.
