x86: fixes some bugs about EFI memory map handling
This patch fixes some bugs of EFI memory handing code.
- On x86_64, it is possible that EFI memory map can not be mapped via
identity map, so efi_map_memmap is removed, just use early_ioremap.
- On i386, the EFI memory map mapping take effect cross paging_init,
so it is not necessary to use efi_map_memmap.
- EFI memory map is unmapped in efi_enter_virtual_mode to avoid
early_ioremap leak.
