scsi: qla2xxx: Preparation for Target MQ.

Browse Source 
In Current code, Req Q 0, RespQ 0 & hardware_lock are the main resources
for sending and process completion of Target IO. These resources are now
referenced behind a new qpair/"struct qla_qpair base_qpair".  Main path
IO handle will access those resources via the qpair pointer in
preparation for Target MQ.
