ut/bdev_nvme: spdk_nvme_probe_poll_async() stub processes only a ctrlr whose trid matches

Browse Source 
Previously spdk_nvme_probe_poll_async() had processed all attaching
controllers. Hence it was not easy to attach multiple controllers in
unit tests.

Besides, add a check to exclude duplicated controllers into ut_attach_ctrlr().

If the target is any SPDK library, we should insert another patch
only to do code movement, but this is a unit test file, and so it
will be acceptable to include code movement in the same file.
