refcount: change EXPORT_SYMBOL markings

Browse Source 
commit d557d1b58b3546bab2c5bc2d624c5709840e6b10 upstream.

Now that kref is using the refcount apis, the _GPL markings are getting
exported to places that it previously wasn't.  Now kref.h is GPLv2
licensed, so any non-GPL code using it better be talking to some
lawyers, but changing api markings isn't considered "nice", so let's fix
this up.
