Matthew Wilcox (Oracle) 5a74ac4c4a idr: Fix idr_get_next_ul race with idr_remove ...

Commit 5c089fd0c7 ("idr: Fix idr_get_next race with idr_remove")
neglected to fix idr_get_next_ul().  As far as I can tell, nobody's
actually using this interface under the RCU read lock, but fix it now
before anybody decides to use it.
