ASoC: SOF: topology: fix memory leak in snd_sof_load_topology 
When the topology filename contains "dummy" and tplg_cnt is 0, the
function returns -EINVAL directly without freeing the tplg_files
allocated by kcalloc() at line 2497. This leaks memory on every
such topology load attempt.

Fix this by setting ret = -EINVAL and jumping to the out: label,
which already handles the kfree(tplg_files) cleanup.

Fixes: 99c159279c ("ASoC: SOF: don't check the existence of dummy topology")
