AzureIoT submodule fails to compile due to Werror-maybe-uninitialized

[sieren]

Hardware:

Board: ESP32 Dev Module / Wroom Kit etc.
Core Installation version: various (xtensa-esp32-elf-osx-1.22.0-80-g6c4433a-5.2.0)
IDE name: IDF component, CMake Build system
Flash Frequency: 40Mhz
PSRAM enabled: no
Upload Speed: 115200
Computer OS: Mac OSX & Linux

Description:

Compiling as an IDF component (Cmake, C++14 enabled) fails due to -Werror=maybe-uninitialized.
I submitted a fix to the submodule a while ago: VSChina/ESP32_AzureIoT_Arduino#15 but it seems like it is no longer maintained by @lirenhe who added it originally to this repo.

/home/travis/build/sieren/HomeControl/components/arduino-esp32/libraries/AzureIoT/src/az_iot/iothub_client/src/iothubtransport_mqtt_common.c:1058:32: error: 'request_id' may be used uninitialized in this function [-Werror=maybe-uninitialized]
 if (request_id == msg_entry->packet_id)
              ^```

Merged and therefore closed :)
