Remove kmem map
Now that the slab allocator doesn't use kernel virtual memory any more,
this map has become irrelevant.
* kern/slab.c (KMEM_MAP_SIZE): Remove macro.
(kmem_map_store, kmem_map): Remove variables.
(slab_init): Remove call kmem_submap.
* kern/slab.h (kmem_map): Remove extern declaration.
