Suppressing warnings on -Wextra for STM32WB55 #111

Closed hedger closed 2 years ago

hedger commented 2 years ago

In our project https://github.com/flipperdevices/flipperzero-firmware, we enabled -Wextra for all code, and some warnings popped up in libusb_stm32 code we're using for STM32WB55. This PR brings code to suppress them.
