scsi: libiscsi: Improve conn_send_pdu API
The conn_send_pdu API is evil in that it returns a pointer to an iscsi_task, but that task might have been freed already so you can't touch it. This patch splits the task allocation and transmission, so functions like iscsi_send_nopout() can access the task before its sent and do whatever bookkeeping is needed before it is sent.
