lib/nvmf: Use qpair_get_listen_trid() to find a subsystem listener

Browse Source 
There is a public API spdk_nvmf_qpair_get_listen_trid() and it can
get trid of the specified qpair safely for any transport including
pluggable transports.

The API was overlooked when implementing the multipath feature for
NVMe-oF target. trid pointer was added to struct spdk_nvmf_qpair and
was used to find a subsystem listener.

However, pluggable transports got seg. fault because trid of the
qpair was not set.

To avoid such segmentation fault for any transport, change
nvmf_ctrlr_create() to use spdk_nvmf_qpair_get_listen_trid().

The struct spdk_nvmf_qpair is located in the public header file,
and so leave the added trid for now. It will be deprecated eventually.
