Commit c60d36b4d1
* UefiCpuPkg/SmmCpu: Block access-out only when static paging is used
updated page fault handler to treat SMM access-out as allowed
address when static paging is not used.
But that commit is not complete because the page table is still
updated in SetUefiMemMapAttributes() for non-SMRAM memory. When SMM
code accesses non-SMRAM memory, page fault is still generated.
This patch skips to update page table for non-SMRAM memory and
page table itself.
