[block] Ignore redundant xfer_window_changed() messages

For some block device protocols, the active path may continue to
receive xfer_window_changed() notifications during normal use.  These
currently result in the active path being erroneously closed.

Fix by ignoring any xfer_window_changed() messages if this path is
already the active path.
