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. Signed-off-by: Daniel P.
