Clear up trailing NULs in cam_strvis. cam_xpt.c: Nuke an experimental quirk entry for the Toshiba 3401. The real problem with this device turned out to be a bug in the aic7xxx driver that was fixed months ago. Add a quirk entry to inhibit multiple lun scanning and serial number probing of DPT RAID volumes. My DPT controller hangs up solid when I do either of these things to a RAID 1 volume.
