Fix for linode module requiring name for state=restarted (untested, rebased, migrated) (#24827)

* Rm check for unused 'name' arg for restarted.

The module docs claim 'name' is not required for
restarted state, and the code doesn't seem to use
it is.

* Better error msg for linode 'restarted' state.

* Remove the eval() and loop over args.

* Fix use of eval(args), and cleanups.

* linode 'stopped' state doesnt need name either

Fixes #3873
