Matthew Wilcox (Oracle) d8b8731afb XArray: Fix xas_pause for large multi-index entries ...

commit c36d451ad3 upstream.

Inspired by the recent Coverity report, I looked for other places where
the offset wasn't being converted to an unsigned long before being
shifted, and I found one in xas_pause() when the entry being paused is
of order >32.
