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.
