The pool_index field was renamed to pool_index_plus_1, but the
out-of-bounds diagnostic in stack_depot_fetch() still accesses the old
field.  Looking up a handle whose pool index is outside stack_pools
therefore raises "There is no member named pool_index" instead of printing
the diagnostic and returning an empty result.

Use the already decoded pool_index variable in the diagnostic.
