selftests/bpf: test_xsk: fix memory leak in testapp_stats_rx_dropped()

Browse source

testapp_stats_rx_dropped() generates pkt_stream twice. The last
generated is released by pkt_stream_restore_default() at the end of the
test but we lose the pointer of the first pkt_stream.

Release the 'middle' pkt_stream when it's getting replaced to prevent
memory leaks.
