Improve the dynamic binding OOB error message when binding.size is defaulted.

Browse Source 
A common error when using dynamic offset bindings is to forget to set
the size of the binding, which causes all offsets != 0 to produce an
error. Make the error more explicit when that happens to guide
developers.
