esp: transition to message out phase after SATN and stop command
The SCSI bus should remain in the message out phase after the SATN and stop
command rather than transitioning to the command phase. A new ESPState variable
cmdbuf_cdb_offset is added which stores the offset of the CDB from the start
of cmdbuf when accumulating extended message out phase data.
Currently any extended message out data is discarded in do_cmd() before the CDB
is processed in do_busid_cmd().
