gpu: nvgpu: fix sched get_params for 0 timeslice

Browse Source 
When the TSG is initialized, the timeslice is initially set to 0,
which is a flag for using the default timeslice.

The sched get_params ioctl was returning 0 in this case; instead,
call gk20a_tsg_get_timeslice() to get the correct value.
