When I looked at main and releng/14.1 source I did not see
the atomic_load_int use that is in your patch (without any
-/+ related to the line):

        old = atomic_load_int(&m->ref_count);

I saw just:

        old = &m->ref_count;

including when I look via:

https://cgit.freebsd.org/src/blame/sys/vm/vm_page.c#n4275
or:
https://cgit.freebsd.org/src/blame/sys/vm/vm_page.c?h=releng/14.1#n4090

So you may have other changes that should be involved
that your patch does not apply.
