gpu: nvgpu: report only unhandled methods

Browse Source 
Some methods are implemented in SW, and it is expected that
nvgpu driver gets illegal method interrupts for these.
Do not report illegal method error if related method could
be handled. It avoids reporting false errors to 3LSS and
more importantly avoids entering SW quiesce state.
