Value type controller properties with [From*] fail with NullRef exception when no value is available

[pranavkm]

Scenario:

public class TestController
{
   [FromBody]
   public int Value { get; set; }

  [HttpPost]
   public int DoPost()
   {
      return Value;
   }
}

When an invalid value is posted (for instance posting a JSON string here), the binder returns a null value. Attempting to set null on a value type property fails with a null ref.
