Andrew Cooper 576fca515e tools/libxl: Remove unconditional XEN_DOMCTL_set_llc_colors hypercall ...

Hypercalls are not free; cache colouring is an experimental feature, and
ignoring an -EOPNOTSUPP is bad form.

Now that Xen has been fixed to initialise colouring information correctly for
domains, xc_domain_set_llc_colors() only needs calling for domains with
explicit configuration.

Rearrange the logic to avoid the hypercall in the general case, leaving a
comment explaining why it is performed so early.
