Fix BC6h decoder

The alpha channel was never written to the result because it was only
ever set in the variable's default value, which would only be set by
the default constructor. Since the output is only cast as a Color,
and never constructed, then the constructor was never called on the
output, and the alpha was never set. This CL sets the alpha channel
on both copy operations, making sure the output alpha is set.
