i2c: stm32: do not set the STOP condition on error
Current function stm32_i2c_message_xfer is sending a STOP
whatever the result of the transaction is. This can cause issues
such as making the bus busy since the controller itself is already
sending automatically a STOP when a NACK is generated.
Thanks to Jorge Ramirez-Ortiz for diagnosing and proposing a first
fix for this. [1]
