klist: Fix object alignment on 64-bit.

Browse Source 
commit 795abaf1e4 upstream.

Commit c0e69a5bbc ("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.
