LX200_Mount opens a bogus SkyFi connection to a nonexistent server

[je-lamiaud]

When a "lx200://" type connection is requested while the lx200 TCP server is not yet up, the indigo_mount_lx200 reports having open the connection. Of course, not any action on the mount succeeds, as there is no real connection. I had this problem both on Linux and MacOS.

The cause is _opensocket reporting a valid socket value, event though this socket connection failed. Please find below a patch which fixed the issue for me:
