thunderbolt: Fix to check return value of ida_simple_get
[ Upstream commit 9aabb68568b473bf2f0b179d053b403961e42e4d ]
In enumerate_services, ida_simple_get on failure can return an error and
leaks memory. The patch ensures that the dev_set_name is set on non
failure cases, and releases memory during failure.
