[PATCH] ncr5380: Correctly clear command pointers and lists after bus reset

Commands subject to exception handling have to be returned to the scsi mid-layer. Make sure that the various command pointers and command lists in the low-level driver are correctly cleansed of the affected commands. This fixes bugs that I accidentally introduced in commit 62717f537e1b ("ncr5380:
