[PATCH] scsi: aic7xxx: Fix scsi_device reference leak in ahc_dump_target_state()

[Wentao Liang]

ahc_dump_target_state() looks up each LUN with
scsi_device_lookup_by_target(), which returns the device with a
reference held, but the reference is never dropped. Put the device once
its state has been dumped.
