2e07e06330 gpu: nvgpu: Remove unnecessary use of ACCESS_ONCE() 
ACCESS_ONCE() is used for making sure that in a given place of code
access a variable exactly once. It prevents compiler rearranging the
read from happening earlier.

Remove its use from cases where rearranging of the read does not
create problems.
