The "raising min_free_kbytes" pr_info message in
set_recommended_min_free_kbytes() and the "min_free_kbytes is not updated
to" pr_warn in calculate_min_free_kbytes() can spam the kernel log when
called repeatedly.
Switch the pr_info in set_recommended_min_free_kbytes() and the pr_warn in
calculate_min_free_kbytes() to their _ratelimited variants to prevent the
log spam for this message.
