IB/ipath: Change get_user_pages() usage to always NULL vmas
The static helper routine, __ipath_get_user_pages(), accepts a vma arg, but current use always passes NULL. This has caused some confusion associated with the correct use of this argument, but since the current use case doesn't require the flexiblity, the best thing to do is to simplfy the code to always pass NULL to get_user_pages().
