gpu: nvgpu: Change in scheduler class for threads

Browse Source 
As per one of the requirement priority of interrupt threads in
qnx should be changed to 21 with SCHED_RR class. NVGPU driver
is creating threads with FIFO class. This makes delay in scheduling
other interrupt threads.

This is added to change the schduler class to RR.
