The two unsigned int variables nb_in_sg and nb_out_sg can be assigned
signed value (-EINVAL) from sg_nents_for_len().
Furthermore they are used only by dma_map_sg and dma_unmap_sg which wait
for an signed int, so they must be set as int.
Fixes: 6c2b74d4774f ("crypto: sahara - check return value of sg_nents_for_len")
