With recent changes libreduce should provide correct buffers
if the driver doesn't support SGL in/out. This patch verifies
that we don't use SGLs when they are not supported.
Since even a single buffer can be split on 2MB page
boundary, it is not enough just to check iovs count.
Added asserts that the first elements of mbufs are
not null to avoid scan build errors
