sparc/leon: Remove on-stack cpumask var
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_subset() and cpumask_first_and() to avoid the need for a
temporary cpumask on the stack.
