Brett Creeley 3b8f7a24d1 vfio/pds: Only use a single SGL for both seq and ack
Since the seq/ack operations never happen in parallel there
is no need for multiple scatter gather lists per region.
The current implementation is wasting memory. Fix this by
only using a single scatter-gather list for both the seq
and ack operations.
