gpu: nvgpu: use u32 for timeout API duration

Browse Source 
A negative value in the timeout duration does not have any special uses,
so change the duration type to u32 (from just int). Delete some
unnecessary typecasts to int.

Also change MAX_SCHEDULE_TIMEOUT to ULONG_MAX in default gr idle timeout
because the value is in milliseconds instead of scheduling units and to
drop unnecessary Linux dependency.
