sched_ext: Fix stray scx_root usage in task_can_run_on_remote_rq()
task_can_run_on_remote_rq() takes @sch but it is using scx_root when incrementing SCX_EV_DISPATCH_LOCAL_DSQ_OFFLINE, which is inconsistent and gets in the way of implementing multiple scheduler support. Use @sch instead. As currently scx_root is the only possible scheduler instance, this doesn't cause any behavior changes.
