Shuhei Matsumoto 604b4503c4 lib/nvmf: Add nvmf_transport_qpair_abort_request()
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.
