sched_ext: Fix the running task keeping its protection into bypass

Protection ends when the scheduler enters bypass, so that bypass scheduling
can cut every task's slice. scx_bypass() clears it for the queued tasks by
cycling them, and strips the running task's in the same walk over
rq->scx.runnable_list. The running task is never on that list.
set_next_task_scx() takes it off and put_prev_task_scx() puts it back, so
the strip never runs. A protected running task then keeps its slice into
bypass, where the tick's attempts to cut it are refused.

Strip the running task's protection outside the walk.
