[Errno 98] Address already in use

[ChrisSutton123]

Running HA on Hassbian, Since update to 0.70.1, I am getting the following error on my Yamaha music cast device:-

2018-06-04 18:46:08 DEBUG (Thread-9) [homeassistant.components.media_player.yamaha_musiccast] known_hosts: []
2018-06-04 18:46:08 ERROR (Thread-9) [homeassistant.components.media_player.yamaha_musiccast] [Errno 98] Address already in use

My yaml configuration is:

• platform: yamaha
  host: 192.168.1.6
  port: 5006
  name: WXA-50
  zone_names:
  Main_Zone: "Bedroom Room"

• platform: yamaha_musiccast
  host: 192.168.1.7
  port: 5007

As a consequence if this error the device is not registered as a usable entity

Root cause is here: https://github.com/jalmeroth/pymusiccast/blob/0.1.6/pymusiccast/__init__.py#L97

pymusiccast.McDevice initializes a UDP socket for each device, and the second time that runs it fails.
