Subject: [PATCH 4.9 145/271] spi: spi-fsl-spi: call spi_finalize_current_message() at the end

From: Christophe Leroy <christophe.leroy@....fr>

[ Upstream commit 44a042182cb1e9f7916e015c836967bf638b33c4 ]

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")
