[PATCH] zsmalloc: remove null check from destroy_handle_cache()

[PATCH] zsmalloc: remove null check from destroy_handle_cache()

[Sergey Senozhatsky]

We can pass a NULL cache pointer to kmem_cache_destroy(),
because it NULL-checks its argument now. Remove redundant
test from destroy_handle_cache().
