Users were seeing floods of `config_sync` events when autoexpand was enabled. This happened because all "disk status change" udev events invoke the autoexpand codepath, which calls zpool_relabel_disk(), which in turn cause another "disk status change" event to happen, in a feedback loop. Note that "disk status change" happens every time a user calls close() on a block device. This commit breaks the feedback loop by only allowing an autoexpand to happen if the disk actually changed size.
