x86/mm: disable instrumentations of mm/pgprot.c

x86/mm: disable instrumentations of mm/pgprot.c

Commit 4867fbbdd6b3 ("x86/mm: move protection_map[] inside the platform")
moved accesses to protection_map[] from mem_encrypt_amd.c to pgprot.c.  As
a result, the accesses are now targets of KASAN (and other
instrumentations), leading to the crash during the boot process.

Disable the instrumentations for pgprot.c like commit 67bb8e999e0a
("x86/mm: Disable various instrumentations of mm/mem_encrypt.c and
mm/tlb.c").

Before this patch, my AMD machine cannot boot since v6.0-rc1 with KASAN
enabled, without anything printed.  After the change, it successfully
boots up.
