crypto: caam - Handle errors in dma_map_sg_chained
Currently dma_map_sg_chained does not handle errors from the
underlying dma_map_sg calls. This patch adds rollback in case
of an error by simply calling dma_unmap_sg_chained for the ones
that we've already mapped.
All current callers ignore the return value so this should have
no impact on them.
