9d56291366 [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.

1c3f0b8e07 Change struct marker users 
Prior to use struct marker in the linux kernel markers, we need to clean
two drivers which use this structure name.

Change bonding driver types :
- struct marker to struct bond_marker.
- marker_t to bond_marker_t.
- marker_header to bond_marker_header.
- marker_header_t to bond_marker_header_t.

Change qla4xxx struct marker_entry usage :
- Change struct marker_entry for struct qla4_marker_entry.
