Subject: [PATCH] spi: spi-fsl-spi: call spi_finalize_current_message() at the
 end

spi_finalize_current_message() shall be called once all
actions are finished, otherwise the last actions might
step over a newly started transfer.

Fixes: c592becbe704 ("spi: fsl-(e)spi: migrate to generic master queueing")
