Fix T50830: Wrong context when calling surfacedeform_bind

The custom poll function for surfacedeform_bind seems to have caused
issues when calling it from Python. Fixed by using the generic modifier
poll function, and setting the button to be active or not in the
Python UI code instead. (there might be a better way, but for now this
works fine)
