stm32: Wait for transmission to complete before returning from spi_transfer()
It's possible for the SCLK pin to still be updating even after the
last byte of data has been read from the receive pin. (In particular
in spi mode 0 and 1.) Exiting early from spi_transfer() in this case
could result in the CS pin being raised before the final updates to
SCLK pin.
Add an additional wait at the end of spi_transfer() to avoid this
issue.
