x86/resctrl: Always initialise rid field in rdt_resources_all[]
x86 has an array, rdt_resources_all[], of all possible resources.
The for-each-resource walkers depend on the rid field of all
resources being initialised.
If the array ever grows due to another architecture adding a resource
type that is not defined on x86, the for-each-resources walkers will
loop forever.
Initialise all the rid values in resctrl_arch_late_init() before
any for-each-resource walker can be called.
