Darek Stojaczyk f93b6fb0a4 bdev: defer unregister untill *all* descriptors are closed ... We used to wait only for those descriptors which specified the hotremove notification callback. The bdev could've been removed before the descriptor was closed and the subsequent spdk_bdev_close would simply segfault. This patch modifies spdk_bdev_unregister to always wait for all descriptors to be closed before actually unregistering the bdev. This consolidates the bdev unregister behavior for descriptors with and without the hotremove callback.
