[PATCH] cciss: use lun reset not target reset

["Stephen M. Cameron" <scameron@beardog.cce.hp.com>]

From: Stephen M. Cameron <scameron@beardog.cce.hp.com>

In the scsi part of the driver (for tape drives and medium changers)
the device reset error handler attempts to use a target reset rather
than a lun reset.  If there is some shared tape drive library, this
could be potentially disruptive to other hosts trying to use the
tape library.  Use lun reset instead to only reset the lun not the
whole target.
