platform/x86: think-lmi: Fix kobject cleanup
commit 9110056fe10b0519529bdbbac37311a5037ea0c2 upstream.
In tlmi_analyze(), allocated structs with an embedded kobject are freed
in error paths after the they were already initialized.
Fix this by first by avoiding the initialization of kobjects in
tlmi_analyze() and then by correctly cleaning them up in
tlmi_release_attr() using their kset's kobject list.
Fixes: a40cd7ef22fb ("platform/x86: think-lmi: Add WMI interface support on Lenovo platforms")
Fixes: 30e78435d3bf ("platform/x86: think-lmi: Split kobject_init() and kobject_add() calls")
