78ff96bb73 bdev_xnvme: free bdev_xnvme structure after device is fully unregistered
Fix for the issue 2702.
spdk_bdev plugin crashes while handling xnvme devices.

xnvme_queue_term gets invoked after the bdev_xnvme_free executes and
frees the xnvme structures. xnvme_queue_term references the xnvme->dev
structure, after it is freed, resulting in a segmentation fault.

Implemented a bdev_xnvme_destruct_cb, that frees the xnvme structures
after the xnvme_queue_term invokes and the device is fully unregistered.

cfe5d18823 bdev/xnvme: enable polling on io_uring_cmd
Fixes #2708 for io_uring_cmd.

This is a minimal approach to enabling polling for bdev_xnvme. Ideally,
more would be done, however, there are several blockers to remove when
doing so. Thus, this commit only enables polling on
io_mechanism=io_uring_cmd.

69bcb185f3 bdev/xnvme: save xnvme bdevs from runtime
config_json callback is used to preserve all
bdevs that were created during application runtime.

xnvme bdev module was missing this callback.

While here, io_mechanism is now saved in the bdev_xnvme
structure for reference in the config_json.
Haven't seen an option to pull this from xnvme itself.

43c5293e16 xnvme: Fix memory leak for xnvme dev.
If we use dd or bdevperf to run the xnvme bdev.
the destruct function of xnvme misses to free
dev while destructing bdev_xnvme.

xnvme_dev_close does free dev, and we can put it
in bdev_xnvme_free.

Meanwhile fixing cleanup for delete_xnvme_bdev.

This rpc for delete_xnvme_bdev doesn't really cleanup
to remove the bdev from the list and  free the names.

Fixes issue: #2654

This change fixes the lower performance issue of the
xNVMe BDEV for libaio and io_uring backends. There is no
drop in the performance for the io_uring passthrough backend.
