Log message:
Protect the freelists of transfer descriptors with the appropriate spl
so that we do not end up allocating two times new descriptors.
This happens if a thread finds an empty list, start allocating, got
interrupted and the interrupt also finds an empty list.
Fix an issue reported by Nils Frohberg.
