Nikita Zhandarovich 4c0ac81a17 crypto: safexcel - Add error handling for dma_map_sg() calls ...

[ Upstream commit 87e02063d07708cac5bfe9fd3a6a242898758ac8 ]

Macro dma_map_sg() may return 0 on error. This patch enables
checks in case of the macro failure and ensures unmapping of
previously mapped buffers with dma_unmap_sg().
