klist: Fix object alignment on 64-bit.
commit 795abaf1e4e188c4171e3cd3dbb11a9fcacaf505 upstream.
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.
