mm: replace custom bad page map ratelimiting logic

Patch series "mm: replace custom ratelimiting logic".

The kernel has a perfectly cromulent and mostly-equivalent variant in
lib/ratelimit.c that can be used.


This patch (of 2):

The current logic (allow up to $BURST prints per minute) can be entirely
replaced by the generic version in lib/ratelimit.c, used around the
kernel.

Do so.  The only functional difference should be that the new logs will
read something like:

KERN_WARNING "print_bad_page_map: %d callbacks suppressed\n", ...

But that should be fine enough.
