Check the return value of eglChooseConfig
The EGL specs say that eglChooseConfig doesn't update num_config
if it returns a failure (which is exactly what
Translator/EGL/EglImp.cpp does). Therefore, if this function
returned a failure (e.g. due to an unsupported egl attribute),
nConfigs was left untouched, meaning that the configs array
was left uninitialized but treated as if it was full of valid
configs.
