I've solved the problem. The problem was in the cc110x gpio initialization.
You should use:
const cc110x_params_t cc110x_params[] = {
    {
        .spi  = 0,
        .cs   = GPIO_PIN(0,3),
        .gdo0 = GPIO_PIN(0,0),
        .gdo1 = GPIO_PIN(0,6),
        .gdo2 = GPIO_PIN(0,2)
    },
};
instead of pure numbers.
