mm, page_alloc: remove setup_pageset()

mainline inclusion
from mainline-5.11-rc1
commit 69a8396a
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4MWJF
CVE: NA

-------------------------------------------------

We initialize boot-time pagesets with setup_pageset(), which sets high and
batch values that effectively disable pcplists.

We can remove this wrapper if we just set these values for all pagesets in
pageset_init().  Non-boot pagesets then subsequently update them to the
proper values.

No functional change.
