hw/char/stm32l4x5_usart: Fix memory corruption by adding correct class_size
"make check-qtest-aarch64" recently started failing on FreeBSD builds, and valgrind on Linux also detected that there is something fishy with the new stm32l4x5-usart: The code forgot to set the correct class_size here, so the various class_init functions in this file wrote beyond the allocated buffer when setting the subc->type field.
