crypto: support scatter-gather in software drivers

This patch introduces RTE_CRYPTODEV_FF_MBUF_SCATTER_GATHER feature flag
informing that selected crypto device supports segmented mbufs natively
and doesn't need to be coalesced before crypto operation.

While using segmented buffers in crypto devices may have unpredictable
results, for PMDs which doesn't support it natively, additional check is
made for debug compilation.
