Sergey Senozhatsky 02f7b4145d zsmalloc: fix a null pointer dereference in destroy_handle_cache() 
If zs_create_pool()->create_handle_cache()->kmem_cache_create() or
pool->name allocation fails, zs_create_pool()->destroy_handle_cache()
will dereference the NULL pool->handle_cachep.

Modify destroy_handle_cache() to avoid this.
