sched_ext: Build fix for !CONFIG_SMP
move_remote_task_to_local_dsq() is only defined on SMP configs but
scx_disaptch_from_dsq() was calling move_remote_task_to_local_dsq() on UP
configs too causing build failures. Add a dummy
move_remote_task_to_local_dsq() which triggers a warning.

Fixes: 4c30f5ce4f7a ("sched_ext: Implement scx_bpf_dispatch[_vtime]_from_dsq()")
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202409241108.jaocHiDJ-lkp@intel.com/
