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

Browse source

testapp_xdp_shared_umem() generates pkt_stream on each xsk from xsk_arr,
where normally xsk_arr[0] gets pkt_streams and xsk_arr[1] have them NULLed.
At the end of the test pkt_stream_restore_default() only releases
xsk_arr[0] which leads to memory leaks.

Release the missing pkt_stream at the end of testapp_xdp_shared_umem()
