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.
