WebKit fails IETC :indeterminate and input type=radio test.

As per the HTML spec http://www.whatwg.org/specs/web-apps/current-work/multipage/the-input-element.html#dom-input-indeterminate,
only checkbox input type should respect the indeterminate state.
Removed the support for indeterminate state for radio input types.
