x86: simplify vmalloc_sync_all
vmalloc_sync_all() is only called from register_die_notifier and
alloc_vm_area. Neither is on any performance-critical paths, so
vmalloc_sync_all() itself is not on any hot paths.
Given that the optimisations in vmalloc_sync_all add a fair amount of
code and complexity, and are fairly hard to evaluate for correctness,
it's better to just remove them to simplify the code rather than worry
about its absolute performance.
