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.
