anv: Stop returning VK_ERROR_INCOMPATIBLE_DRIVER

From the Vulkan 1.1 spec:

    "Vulkan 1.0 implementations were required to return
    VK_ERROR_INCOMPATIBLE_DRIVER if apiVersion was larger than 1.0.
    Implementations that support Vulkan 1.1 or later must not return
    VK_ERROR_INCOMPATIBLE_DRIVER for any value of apiVersion."
