The per-VMA locks have been around for several years. They've had some
bugs worked out of them and have seen quite wide use. However, they
are still only available when architectures explicitly enable them.
Remove the conditional compilation around the per-VMA locks, making
them available on all architectures and configs.

I've grepped around in arch-specific code in the architectures that
weren't already opted in to look for stuff that takes the mmap lock in
write mode and manually mutates VMAs, and couldn't find anything, so I
think this is correct.
