Remove several unnecessary experimental_backends check 

Window flags can be set whichever backend we use, we will ignore then in
paint_preprocess. free_paint can be called whichever backend we use,
they just do nothing if we use experimental backends.

Others should rather just check if backend_data is NULL.

Making the code slightly more understandable, also making the eventual
removal of these checks easier.
