a12b879027 cpu/stm32f1: spi_transfer_bytes proper counting. 
The transferred bytes were being counted more than once because of a +=
when calling spi_transfer_byte().

This patch should also handle errors from spi_transfer_byte() better
since it is now possible to detect errors _after_ the first byte has
been successfully sent.
