i2c: stm32: remove unused stop parameter in start & reload handling

Functions stm32_i2c_message_start and stm32_i2c_handle_reload
both get a stop boolean indicating if the transfer should end with
a STOP or not.  However no specific handling is needed in those
functions hence remove the parameter.
