socket: Launch socket_poller only if connect succeeded

  Backport of 92abe07 from master

For an encrypted connection, sockect_connect() used to launch
socket_poller() in it's own thread (ON by default), even if the connect
failed. This would cause two unrefs to be done on the transport, once in
socket_poller() and once in socket_connect(), causing the transport to
be freed and cleaned up. This would cause further reconnect attempts
from failing as the transport wouldn't be available.

By starting socket_poller() only if connect succeeded, this is avoided.
