Shakeel Butt bb8e8f427f x86/resctrl: Fix potential memory leak 
commit ab6a2114433a3b5b555983dcb9b752a85255f04b upstream.

set_cache_qos_cfg() is leaking memory when the given level is not
RDT_RESOURCE_L3 or RDT_RESOURCE_L2. At the moment, this function is
called with only valid levels but move the allocation after the valid
level checks in order to make it more robust and future proof.

 [ bp: Massage commit message. ]
