Hugh Dickins 42c36f63ac vm: fix vm_pgoff wrap in upward expansion ...

Commit a626ca6a65 ("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.
