firewire: fw-sbp2: correctly dereference by container_of
Replace a cast with a container_of(). As long as nobody reorders the structure elements, they do the same thing, but container_of() is more readable. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> (added complete_command_orb) Acked-by: Kristian Høgsberg <krh@redhat.com>
