yaid.c (cancel_proxy): Reorder destruction a little.

Alas, `selbuf_enable' can invoke its per-line function, in this case
`client_line', immediately.  So we need to make sure we've detached this
proxy structure before that happens: if we do it afterwards, we risk
clobbering any new proxy that `client_line' has acquired in the
meantime.
