efi_loader: Handle GD_FLG_SKIP_RELOC

If the EFI runtime services pointers are relocated even though
relocation is skipped, it corrupts some other data resulting in some
unexpected behaviour.

In this specific case, it overwrote some page table entries resulting in
the device memory address range's mappings getting removed. Eventually,
after the completion of efi_runtime_relocate(), when a driver tries to
access its device's registers it crashes since the mappings are absent.
