Lukasz Wojciechowski f25fe0d5e3 distributor: fix return pkt calls in single mode 
In the single legacy version of the distributor synchronization
requires continues exchange of buffers between distributor
and workers. Empty buffers are sent if only handshake
synchronization is required.
However calls to the rte_distributor_return_pkt()
with 0 buffers in single mode were ignored and not passed to the
legacy algorithm implementation causing lack of synchronization.

This patch fixes this issue by passing NULL as buffer which is
a valid way of sending just synchronization handshakes
in single mode.
