Bug 999351 - Fix an IPC leak by clearing MessageChannel resource before destruction. r=bent

Once we have a channel error (like, child process dies) we don't immediately do

queued and eventually get freed when the channel is destroyed. This patch clears
the resource earlier whenever there is an error, or the channel is closed.
