commit ce0fc6db38decf0d2919bfe783de6d6b76e421a9 upstream.
Deal gracefully with a NULL or empty scatterlist which can happen
if both cryptlen and assoclen are zero and we're doing in-place
AEAD encryption.
This fixes a crash when this causes us to try and map a NULL page,
at least with some platforms / DMA mapping configs.
