powercap: intel_rapl: Optimize rp->domains memory allocation 



In the memory allocation of rp->domains in rapl_detect_domains(), there
is an additional memory of struct rapl_domain allocated, optimize the
code here to save sizeof(struct rapl_domain) bytes of memory.

Test in Intel NUC (i5-1135G7).
