gpu: nvgpu: maintain authorized devices in TSG

Browse Source 
When the TSG is successfully created first time or is opened with share
token, the device instance id associated with the CTRL fd will be added
to the TSG private data structure as authorized device instance ids.

This is used for a security check when creating a TSG share token with
nvgpu_tsg_get_share_token.
