x86/efi: Test for EFI_MEMMAP functionality when iterating EFI memmap
Both efi_find_mirror() and efi_fake_memmap() really want to know whether the EFI memory map is available, not just whether the machine was booted using EFI. efi_fake_memmap() even has a check for EFI_MEMMAP at the start of the function. Since we've already got other code that has this dependency, merge everything under one if() conditional, and remove the now superfluous check from efi_fake_memmap().
