sched_ext: Update scx_dispatch_dequeue() comments
Remote consumption now reaches the !dsq branch with holding_cpu set,
just like dispatch_to_local_dsq(). Clearing holding_cpu in this branch
also tells dispatch_to_local_dsq() that it lost to a dequeue. The
dsq-present branch races with unlink_dsq_and_switch_rq_lock(), not
dispatch_to_local_dsq().
Update both comments to describe the current transfer paths and race
semantics. No functional change.
