stm32/pyb_can: Include requested CAN baudrate in matching error.

Browse Source 
This is redundant for bxCAN, but for CAN-FD with BRS it's otherwise unclear
which set of parameters (baudrate & sample_point or brs_baudrate &
brs_sample_point) failed to match. This makes finding a valid combination
extra annoying.
