x86: bugfix wbinvd() model check instead of family check
wbinvd is supported on all CPUs 486 or later. But,
pageattr.c is checking x86_model >= 4 before wbinvd(), which looks like
an oversight bug. It was first introduced at one place by changeset
d7c8f21a8cad0228c7c5ce2bb6dbd95d1ee49d13 and got copied over to second
place in the same file later.
[ Impact: fix missing cache flush on early-model CPUs, potential data corruption ]
