efi_loader: efi_current_var after SetVirtualAddressMap
Variable efi_current_var is a pointer to a physical memory address that
becomes invalid after SetVirtualAddressMap(). Instead of converting it via
ConvertPointer() simply set it to NULL.
Fixes: b02a707152dc ("efi_loader: enable UEFI variables at runtime")
