Pull SCSI target updates from Nicholas Bellinger:
 "The highlights this round include:

   - enable dual mode (initiator + target) qla2xxx operation. (Quinn +
     Himanshu)

   - add a framework for qla2xxx async fabric discovery. (Quinn +
     Himanshu)

   - enable iscsi PDU DDP completion offload in cxgbit/T6 NICs. (Varun)

   - fix target-core handling of aborted failed commands. (Bart)

   - fix a long standing target-core issue NULL pointer dereference with
     active I/O LUN shutdown. (Rob Millner + Bryant + nab)"
