fd2af7afa9 lib/nvme: stop all NVMe io producers on detach
Now all registered producers should be stopped (unregistered) before
NVMe detach, otherwise NVMe controller cannot be safely detached.

This patch allows to stop all not unregistered io producers before
NVMe detach:

1. Callback to the "struct nvme_io_msg_producer" to stop producer
   started on selected controller.
2. On nvme_io_msg_ctrlr_detach() if there's some unregistered producers,
   stop all before freeing resources.


This approach also fixes issue with not to stop CUSE device when
NVMe controller is detached without unregistering producer (github
issue #1033).

	Fixes #1033

Users already have to poll the admin queue, so embed the io_msg
queue polling there to simplify the API.

72e079a880 lib/nvme: implement external IO processing
This patch allows to send IO requests from external module to the nvme
device.

External module should call nvme_io_msg_ctrlr_start() to start IO message
producer on the controller and enable sending messages.

nvme_io_msg_send() is used to send IO to NVMe driver thread context,
where passed function will be called. Allowing the external module to
issue IO as needed.

NVMe driver users should poll spdk_nvme_io_msg_process() to move forward,
sending IO from external module and process their completions.
