x86: fix some bugs about EFI runtime code mapping
This patch fixes some bugs of making EFI runtime code executable.
- Use change_page_attr in i386 too. Because the runtime code may be
mapped not through ioremap.
- If there is no _PAGE_NX in __supported_pte_mask, the change_page_attr
is not called.
- Make efi_ioremap map pages as PAGE_KERNEL_EXEC_NOCACHE, because EFI runtime
code may be mapped through efi_ioremap.
