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. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
