BUG/MEDIUM: muxes: Use the right argument when calling the destroy method.
When calling the mux "destroy" method, the argument should be the mux
context, not the connection. In a few instances in the mux code, the
connection was used (mainly when the session wouldn't handle the idle
connection, and the server pool was fool), and that could lead to random
segfaults.
This should be backported to 2.1, 2.0, and 1.9
