platform/x86: dell-smbios: Fix memory leaks in build_tokens_sysfs()
We're freeing "value_name" which is NULL, so that's a no-op, but we
intended to free "location_name" instead. And then we don't free the
names in token_location_attrs[0] and token_value_attrs[0].
Fixes: 33b9ca1e53b4 ("platform/x86: dell-smbios: Add a sysfs interface for SMBIOS tokens")
