bug17801.diff1.txt defer unlocking the channels ao2_container till the very
end of ast_do_masquerade.
Otherwise with no lock on the 'channels' ao2_container and releasing the
locks on 'original and clonechan' channel before the linking back into
ao2_container we get corrupted.

Also tried in ast_do_masquerade at done: the following, observing required
locking order - but no better : 
   unlock both channels
   ao2_lock(channels)
   lock both channels 
   unlock both channels  (we should now be ok to ao2_link(channels, XXX)
   ao2_link(channels, original)
   ao2_link(channels, clonechan)
   ao2_unlock(channels)
