There are 2 potential blocking calls when using IoTCredentialProvider… (#223)

* There are 2 potential blocking calls when using IoTCredentialProvider: Curl & Lws.
The curl call already has logging when the curl_easy_perform fails, however the LWS blocking call did not have any logging on failure.

* Corrected the capitalization, added general error message, but also wanted to keep the specific error message for LWS failure
