Call this function from spdk_bdev_mgmt_channel_destroy().
Currently there are no real resources to free, but that
will change in an upcoming patch which adds per-thread
bdev_io caches.
While here, also add a for_each_channel iterator to
call this function on each existing channel during bdev
finish code path.
