set the connected status of a socket after UDP & raw connect

[jepler]

This is a speculative fix for adafruit/Adafruit_CircuitPython_NTP#33

[anecdata]

NTP lib: (edit: v3.1.0, was convenient for testing)

                sock.connect(self._socket_address)
                sock.send(self._packet)
                sock.recv_into(self._packet)

thanks for the quick testing. I hadn't even gotten a board out yet.

[dhalbert]

The .send() was changed to sendto() just now in version 3.1.1 of the NTP library.

Is there any other testing that's needed? I could see this coming up somewhere else...

[anecdata]

I didn't test RAW, only used the (previous, interim) NTP lib to test UDP. Not sure if anyone uses RAW.

[dhalbert]

I will go ahead and merge this. The RAW case seems like it should be the same. We can fix if there's something pathological.
