[IOT - 2413] Fix for Heap-use-after-free issue.

[AddressSanitizer] Heap-use-after-free in InProcServerWrapper.cpp fix.

 if(!interface.empty())
        {
            const string query = string("if=" + interface);
            ocEntityHandlerRequest.query = const_cast<char *>
            		(query.c_str());
        }

Local variable 'query' reference after it goes out of scope
can be a cause for crash.
