shd/mux: Fix race between mux_proc unlink and stop
There is a small race window, where we have a shd proc
without having a connection. That is when we stopped the
last shd running on a process. The list was removed
outside of a lock just after stopping the process.
So there is a window where we stopped the process, but
the shd proc list contains the entry.
