scsi: qla2xxx: Move {get|rel}_sp to base_qpair struct
Currently, qla2x00_[get_sp|rel_sp] routines does {get|release} of srb
resource/srb_mempool directly from qla_hw_data. qla2x00_start_sp() is used to
issue management commands through the default Request Q 0 & Response Q 0 or
base_qpair. This patch moves access of these resources through
base_qpair. Instead of having knowledge of specific Q number and lock to
rsp/req queue, this change will key off the qpair that is assigned to the srb
resource. This lays the ground work for other routines to see this resource
through the qpair.
