Fix random crashes in x86-64 swsusp

Hi!

fix_processor_context was calling functions marked __init on x86-64;
bad idea. Maybe we should memset freed memory to zero so such bugs are
prevented?

Thanks to Rafael for keeping notifying me about this bug, and someone
get me yet another brown paper bag.

Anyway, this should fix it, please apply,
Pavel
