gpu: nvgpu: Fix __nvgpu_set_enabled MISRA 17.7 violations

MISRA Rule-17.7 requires the return value of all functions to be used.
Fix is either to use the return value or change the function to return
void. This patch changes the signature of __nvgpu_set_enabled to
return void since the signature never implied it should return the
final value of the flag. No code within NVGPU was using the return
value anyway.
