Benjamin Gaignard 7352f2c264 spi: mediatek: Avoid NULL pointer crash in interrupt 
commit f83a96e5f0 upstream.

In some case, like after a transfer timeout, master->cur_msg pointer
is NULL which led to a kernel crash when trying to use master->cur_msg->spi.
mtk_spi_can_dma(), pointed by master->can_dma, doesn't use this parameter
avoid the problem by setting NULL as second parameter.

Fixes: a568231f46 ("spi: mediatek: Add spi bus for Mediatek MT8173")
