lib/test_meminit.c: minor test fixes
Fix the following issues in test_meminit.c:
- |size| in fill_with_garbage_skip() should be signed so that it
doesn't overflow if it's not aligned on sizeof(*p);
- fill_with_garbage_skip() should actually skip |skip| bytes;
- do_kmem_cache_size() should deallocate memory in the RCU case.
