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.
