irqchip/sifive-plic: Avoid explicit cpumask allocation on 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_first_and_and() to avoid the need for a temporary cpumask on the stack.
