8818ace2f4 nvme: Don't use stack variable to track request completion
A pointer to a stack variable is passed as an argument to
nvme_completion_poll_cb function, later this variable is used
to track completion in the spdk_nvme_wait_for_completion() function.
If normal scenario a request submitted to the admin queue will be completed
within the function which submitted the request.
spdk_nvme_wait_for_completion() calls nvme_transport_qpair_process_completions
which may return an error to the caller, the caller may exit from the
function which submitted the request and the pointer to the stack variable
will no longer be valid. Thereby the request may not be completed at that time
and completed later (e.g. when the controller/qpair are destroyed)
and that will lead to call to nvme_completion_poll_cb with the pointer
to invalid stack variable.
Fix - Dynamically allocate status structure to track the completion;
Add a new field to nvme_completion_poll_status structure to track status
objects that need to be freed in a completion callback

Fixes #1125

771d759312 lib/nvme: add spdk_nvme_transport_available_by_name
This new api function will enable us to work with custom transports.

This is needed to enable properly parsing and comparing custom transport
IDs that may all resolve to the same enum value.

a1ce725c0a nvme_fabric: enable the discovery_ctrlr admin queue
As the todo states later on in the function, the discovery controller
should really be initialized through traditional methods, but it was
hacked in. For now, enable the admin qpair to get past the non-standard
nature of this controller.

3306e49e24 nvme: introduce probe context data structure and API
Existing NVMe driver uses a global list g_nvme_init_ctrlrs
to track the controllers during initialization, and internal
function will start each controller in the list one by one
until the list is empty.  We introduce a probe context
and move the global list into the context, with the context
we can enable asynchronous probe API in the next patch, also
this can enable parallel probe feature.
