Separate the call sequence for rdt_quirks and MBA feature. This is in preparation to handle vendor differences in these call sequences.

Or simpler:
if (rdt_cpu_has(X86_FEATURE_MBA))
return rdt_get_mem_config(&rdt_resources_all[RDT_RESOURCE_MBA]);
return false;
as rdt_get_mem_config() already returns bool.
