Actually pass the args in salt.function state

**This is against the 2014.1 branch**

Fixes one small problem with the 2014.1 version of salt/states/saltmod.function

Args were not being passed to the function, now they are.

However, saltmod.py is very behind the `develop` version.  It doesn't handle kwargs, it doesn't handle returns correctly, it's missing *a lot* of functionality compared to `develop`'s orchestrate capabilities.  However, at the same time I'm not sure it's a drop-in replacement from `develop`, since we've done so much kwarg work.  In any case, I think because we're so close to the release candidate for the next feature release, we should probably not expend the time/effort required to get it up to standard.

Fixes #12451
