BUG/MEDIUM: stream: Don't call mux .ctl() callback if not implemented

The commit 5ff7d2276 ("BUG/MEDIUM: stream: Properly handle abortonclose when set
on backend only") introduced a regression. Not all multiplexer implement the
.ctl() callback function. Thus we must be sure this callback function is defined
first to call it.

This patch should fix a crash reported by Tristan in the issue #2095. It must be
backported as far as 2.2, with the commit above.
