crypto: omap-sham - fix very small data size handling

Browse source

With very small data sizes, the whole data can end up in the xmit
buffer. This code path does not set the sg_len properly which causes the
core dma framework to crash. Fix by adding the proper size in place.
Also, the data length must be a multiple of block-size, so extend the
DMA data size while here.
