spi: don't unoptimize message in spi_async()
Calling spi_maybe_unoptimize_message() in spi_async() is wrong because
the message is likely to be in the queue and not transferred yet. This
can corrupt the message while it is being used by the controller driver.
spi_maybe_unoptimize_message() is already called in the correct place
in spi_finalize_current_message() to balance the call to
spi_maybe_optimize_message() in spi_async().
Fixes: 7b1d87af14d9 ("spi: add spi_optimize_message() APIs")
