perf/alibaba_uncore_drw: Avoid placing cpumask on the stack
In general it's preferable to avoid placing cpumasks on the stack, as for large values of NR_CPUS these can consume significant amounts of stack space and make stack overflows more likely. Use cpumask_any_and_but() to avoid the need for a temporary cpumask on the stack.
