[ Upstream commit b204aa0f99cfe3c9d796ecfc0bc6f3f89585789e ]
Previously, __spi_sync() and __spi_async() set message->spi to the spi device independently after calling __spi_validate(). __spi_validate() also would conditionally set this if it needed to split the message since it wasn't set yet.
Since both __spi_sync() and __spi_async() call __spi_validate(), we can consolidate this into only setting message->spi once (unconditionally) in __spi_validate(). This will also save any future callers of __spi_validate() from also needing to set message->spi.
