THRIFT-3689 thrift_reconnecting_client start failed when server is not available
Client: Erlang
Patch: laozhp

When first time reconnect without a success call, line 214: Backoff = 2 * R, will cause exception, because R is undefined. Set reconn_time's default value to 0 resolved this.

This closes #895
