x86: unilaterally remove .init mappings

Because of the new 2M alignment of .init and .bss, the existing memory
guarding infrastructure causes a shattered 2M superpage with non-present
entries for .init, and present entries for the alignment space.

Do away with the difference in behaviour between debug and non-debug builds;
always destroy the .init mappings, and reuse the space for xenheap.
