Antony Clince Alex 2d5d8e882f gpu: nvgpu: fix ce interrupt mask update ...

The CE interrupt mask update should not be skipped if the driver doesn't
implement stall or non-stall interrupt handlers. At present, the mask update is
skipped if either is not implemented causing the other to remain disabled which
is not correct.

Update nvgpu_ce_engine_interrupt_mask to always return engine interrupt mask.
