x86/resctrl: Group struct rdt_hw_domain cleanup
domain_add_cpu() and domain_remove_cpu() need to kfree() the child
arrays that were allocated by domain_setup_ctrlval().
As this memory is moved around, and new arrays are created, adjusting
the error handling cleanup code becomes noisier.
To simplify this, move all the kfree() calls into a domain_free() helper.
This depends on struct rdt_hw_domain being kzalloc()d, allowing it to
unconditionally kfree() all the child arrays.
