gpu: nvgpu: Use new kmem API functions (misc)

Use the new kmem API functions in misc gk20a code. Some additional
modifications were also made:

  o  Add a struct gk20a pointer to gk20a_fence to enable proper
     kmem free usage.
  o  Add gk20a pointer to alloc_session() in dbg_gpu_gk20a.c to
     use kmem API for allocating a session.
  o  Plumb a gk20a pointer through the fence creation and deletion.
  o  Use statically allocated buffers for names in file creation.
