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.
