[SCSI] qla4xxx: fix scsi command completion, lun reset and target reset code
This patch contains the following:
1. when hba completion status is good, check for iscsi transport
errors (underflow/overflow) prior to checking the scsi status
2. New firmware requires that one marker iocb be issued for each task
management command. The patch issues marker iocb immediately
following a LUN or Target reset.
