gpu: nvgpu: pass pid/tid from os specific code to common code

Browse Source 
linux driver runs in user's process but qnx driver has dedicate driver
process, so they have different way to get user pid. nvgpu common code
expect calls from os specific code pass pid/tid.

ce/cde open channel for internal use, we use driver pid.
