crypto: sl3516 - drop invalid sg_dma_len checks before DMA mapping

Browse source

sg_dma_len() is only valid after mapping the scatterlist with
dma_map_sg(). However, sl3516_ce_need_fallback() checks it before the
source and destination scatterlists are mapped. Thus, a stale DMA length
that is not a multiple of 16 could incorrectly force a software fallback
when CONFIG_NEED_SG_DMA_LENGTH=y.

Remove the invalid checks; the existing scatterlist length checks are
sufficient.
