Matthew Wilcox f818b82b80 XArray: Mark xa_insert and xa_reserve as must_check ...

If the user doesn't care about the return value from xa_insert(), then
they should be using xa_store() instead.  The point of xa_reserve() is
to get the return value early before taking another lock, so this should
also be __must_check.
