HTTPSClient::connected() hang when _sslClient is NULL

Hi @yaweiw,

We can definitely add a NULL check for prevent it crashing. Could you please share an example sketch and steps to reproduce the issue. I'm curious as to how you are encountering this issue.

uint8_t HTTPSClient::connected()
{
  return (_sslClient ? _sslClient->connected() : false);
}

@sandeepmistry it can easily be reproduced by not having below lines in your ino file.
Adafruit_WINC1500SSLClient sslClient;
AzureIoTHubClient iotHubClient(sslClient);

I think a better fix is changing HTTPAPI_Init in src/httpapi.cpp to fail the SSL client is NULL and logging an error.

Would you have time to submit a PR for this?

@sandeepmistry Ok. I'll have a look later.
