stm32/candev: change candev_stm32_isr flags to uint8_t

[crasbe]

Contribution description

LLVM-17 has a new check that tests bitfields. For single bit integer values in bitfields, the only permitted values are 0 and -1, not 0 and 1.

Testing procedure

This is tested with the Resolute docker container that uses LLVM 17:

buechse@skyleaf:~/RIOTstuff/riot-fresh/RIOT$ docker run --tty -i --rm ca070cefc092 clang --version
Ubuntu clang version 17.0.6 (23ubuntu7)
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/bin

Behavior on master:
