  datapath-windows: Add software checksums for nbl which contain multiple nb

Until now we only needed to compute software checksums on net buffer lists
containing a single net buffer.

This patch allows the software checksums to be applied on a net buffer list
with multiple net buffers. The hard assumption for this, is the net buffers are
part of the same connection. The position of the offsets is pointed by the
layers parameter.

This will be useful for introducing support ip fragments in conntrack.
