Avoid permanently disabled QEMU monitor when UNIX migration fails
If a UNIX migration command is attempt to a UNIX socket which does
not exist, then the monitor is suspended, but never resumed. This
prevents any further use of the monitor
* migration-unix.c: Only call migrate_fd_monitor_suspend() once
connected to the UNIX socket.
