Instead of waiting for ITSDONE in `xs_flags' you could wait for the
associated ecb to be freed, e.g. `while ((ecb->flags & ECB_ALLOC) != 0)'.

This has the added advantage of not relying on implementation details
in the scsi layer, like the `xs' being kept alive long enough (instead
we rely on our own implementation detail that `ecb_free()' just moves
the item between queues).
