crypto: s5p-sss - fix incorrect usage of scatterlists api

commit d1497977fecb9acce05988d6322ad415ef93bb39 upstream.

sg_dma_len() macro can be used only on scattelists which are mapped, so
all calls to it before dma_map_sg() are invalid. Replace them by proper
check for direct sg segment length read.

Fixes: a49e490c7a8a ("crypto: s5p-sss - add S5PV210 advanced crypto engine support")
Fixes: 9e4a1100a445 ("crypto: s5p-sss - Handle unaligned buffers")

[bwh: Backported to 3.2: unaligned DMA is unsupported so there is a different
 set of calls to replace]
