x86: e820: Remove conditional early mapping in parse_e820_ext

This patch ensures that the memory passed from parse_setup_data() is
large enough to cover the complete data structure. That means that the
conditional mapping in parse_e820_ext() can go.

While here, I also attempt not to map two pages if the address is not
aligned to a page boundary.
