server/tests/test_playback: correctly use spice_server_playback_get_buffer

Browse Source 
and spice_server_playback_put_samples. The former retrieves a buffer from a free
list with spice_server_playback_get_buffer, and should be used once via
spice_server_playback_put_samples. The tester previously reused the same buffer
a number of times.
