State machine is different among NVMe-oF transports and is encapsulated to the transport neutral NVMe-oF controller and NVMe-oF qpair. To implement abort operation for each NVMe-oF transport, add a function pointer qpair_abort_request to struct spdk_nvmf_transport_ops and a stub nvmf_transport_qpair_abort_request() to encapsulate which transport is used. The following patches will implement qpair_abort_request for each transport. Each qpair_abort_request() is responsible to call spdk_nvmf_request_complete() for the abort request.
