mm: make dump_page() take a const argument 

JIRA: https://issues.redhat.com/browse/RHEL-27745

This patch is a backport of the following upstream commit:
commit b3a3203309c89061452250f7384507787b7badcb
Author: Matthew Wilcox (Oracle) <willy@infradead.org>
Date:   Tue Feb 27 19:23:32 2024 +0000

    mm: make dump_page() take a const argument

    Now that __dump_page() takes a const argument, we can make dump_page()
    take a const struct page too.
