crypto: sahara - set nb_[in|out]_sg as signed int

Browse Source 
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.
