ALSA: info: Fix llseek return value when using callback
When using callback there was a flow of
ret = -EINVAL
if (callback) {
offset = callback();
goto out;
}
...
offset = some other value in case of no callback;
ret = offset;
out:
return ret;
which causes the snd_info_entry_llseek() to return -EINVAL when there is
callback handler. Fix this by setting "ret" directly to callback return
value before jumping to "out".
Fixes: 73029e0ff18d ("ALSA: info - Implement common llseek for binary mode")
