klist: Fix object alignment on 64-bit.
Commit c0e69a5bbc6f ("klist.c: bit 0 in pointer can't be used as flag") intended to make sure that all klist objects were at least pointer size aligned, but used the constant "4" which only works on 32-bit. Use "sizeof(void *)" which is correct in all cases. Signed-off-by: David S.
