We had not held mutex while removing bdev name or alias from bdev name tree for most cases. Fix these in this patch. spdk_bdev_unregister() already holds g_bdev_mgr.mutex when removing name, and so we do not need to change it. spdk_bdev_close() had not held g_bdev_mgr.mutex. What we want to lock is only when removing name from name tree, that is, calling bdev_name_del() in bdev_unregister_unsafe(). However, we need to keep hierarchical lock ordering. Hence get and free g_bdev_mgr.mutex outside of bdev->internal.mutex.
