Subject: [PATCH] powerpc/mm: Fix makefile for KASAN

In commit 17312f258cf6 ("powerpc/mm: Move book3s32 specifics in
subdirectory mm/book3s64"), ppc_mmu_32.c was moved and renamed.

This patch fixes Makefiles to disable KASAN instrumentation on
the new name and location.

Fixes: f072015c7b74 ("powerpc: disable KASAN instrumentation on early/critical files.")
