gpu: nvgpu: Move kmem_caches to allocator

Instead of using a single static kmem_cache for each type of
data structure the allocators may want to allocate each
allocator now has its own instance of the kmem_cache. This is
done so that each GPU driver instance can accurately track how
much memory it is using.

In order to support this on older kernels a new NVGPU API has
been made,

  nvgpu_kmem_cache_create(struct gk20a *g, size_t size)

To handle the possibility that caches cannot be created with
the same name.

This patch also fixes numerous places where kfree() was wrongly
used to free kmem_cache allocs.
