vm: fix vm_pgoff wrap in upward expansion
commit 42c36f63ac1366ab0ecc2d5717821362c259f517 upstream. Commit a626ca6a6564 ("vm: fix vm_pgoff wrap in stack expansion") fixed the case of an expanding mapping causing vm_pgoff wrapping when you had downward stack expansion. But there was another case where IA64 and PA-RISC expand mappings: upward expansion. This fixes that case too.
