destutil: remove dead code about non-linear updates

IIUC, the non-linear updates no longer happen by default since
6b1fc09c699a (update: change default destination to tipmost descendant
(issue4673) (BC), 2016-02-02), and it was only if they happened by
default that we used to error out, so there is no longer a need to
handle this case.
