In the function __rxe_add_to_pool, the function xa_alloc_cyclic is
called. The return value of the function xa_alloc_cyclic is as below:
"
Return: 0 if the allocation succeeded without wrapping. 1 if the
allocation succeeded after wrapping, -ENOMEM if memory could not be
allocated or -EBUSY if there are no free entries in @limit.
"
But now the function __rxe_add_to_pool only returns -EINVAL. All the
returned error value should be returned to the caller.
