[PATCH] More careful about VMA merging

The VMA merging code can merge vmas which have a ->vm_ops->close() handler.
But this means that per-VMA resources in one of the merged VMAs will not be
freed.

Fix that up by just refusing to merge any VMA's which look "complex": they
have special flags set or they have a ->close handler.
