No longer calling DeferredTextureImageUsageParams' default ctor.

I want to remove SkImage::DeferredTextureImageUsageParams' default ctor.
Before I make that change in Skia, I want to update Chrome to no longer call it.

The default ctor did not initialize all of the members, which lead to surprises.
We could simply initialize all the values to some weird state.
But a better option would be to not allow the object to be created unless it
can be in a valid state.
