Subject[PATCH] 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

I don't think this will lead to a real life bug, but it's easy enough to
change it to be NULL.
