ieee1394: sbp2: fix for SYM13FW500 bridge (Datafab disk)

Fix I/O errors due to SYM13FW500's inability to handle larger request sizes. Reported by Piergiorgio Sartor <piergiorgio.sartor@nexgo.de> for firewire-sbp2 in https://bugzilla.redhat.com/show_bug.cgi?id=436879 This fix is necessary because sbp2's default request size limit has been lifted since 2.6.25-rc1. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Signed-off-by: Jarod Wilson <jwilson@redhat.com>
