mm, slub: use pGp to print page flags

mainline inclusion
from mainline-5.13-rc1
commit 4a8ef190
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I3ZZ8S
CVE: NA

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

As pGp has been already introduced in printk, we'd better use it to make
the output human readable.

Before this change, the output is,
[ 6155.716018] INFO: Slab 0x000000004027dd4f objects=33 used=3 fp=0x000000008cd1579c flags=0x17ffffc0010200

While after this change, the output is,
[ 8846.517809] INFO: Slab 0x00000000f42a2c60 objects=33 used=3 fp=0x0000000060d32ca8 flags=0x17ffffc0010200(slab|head)
