[COMMITTED 2.36] aio: Fix freeing memory

[Aurelien Jarno]

From: Samuel Thibault <samuel.thibault@ens-lyon.org>

The content of the pool array is initialized only until pool_size,
pointers between pool_size and pool_max_size were not initialized by the
realloc call in get_elem so they should not be freed.

This fixes aio tests crashing at their termination on GNU/Hurd.

(cherry picked from commit 0cee4aa92f5b9b213856c8ba1ab84c34d73c943b)
