[PATCH v2] x86/resctrl: fix a NULL vs IS_ERR() static checker warning

The callers don't expect *d_cdp to be set to an error pointer, they only check for NULL. This leads to a static checker warning: arch/x86/kernel/cpu/resctrl/rdtgroup.c:2648 __init_one_rdt_domain() warn: 'd_cdp' could be an error pointer This would not trigger a bug in this specific case
