zed: Fix config_sync autoexpand flood
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.
