gpu: nvgpu: track gr_ctx init state

Browse Source 
On successful obj_ctx allocation, set ctx_initialized member in gr_ctx
to true and when it is true then only invoke free_gr_ctx.

With this we can get rid of tsg->vm check while calling free_gr_ctx.
tsg->vm will go away with multiple address spaces support in TSG.
