sched: core: Fix possible hotplug race in set_cpus_allowed_ptr
Since a CPU may go offline after cpu_active_mask is used
to query active CPUs, set_cpus_allowed_ptr might inadverntently
pass an invalid cpu number to move_queued_task.
Fix this by ensuring that the cpumask op that uses cpu_active_mask
checks the return value.
