IB/rxe: put the pool on allocation failure

[ Upstream commit 6b9f8970cd30929cb6b372fa44fa66da9e59c650 ]

If the allocation of elem fails, it is not sufficient to simply check
for NULL and return.  We need to also put our reference on the pool or
else we will leave the pool with a permanent ref count and we will never
be able to free it.
