sched_ext: Drop the dead SCX_DEQ_CORE_SCHED_EXEC test in dequeue_task_scx()

Browse source

dequeue_task_scx() masks SCX_DEQ_CORE_SCHED_EXEC out of the
SCX_DEQ_SCHED_CHANGE decision, but the test can never fire: the incoming
flags are an int of generic DEQUEUE_* bits while the flag is bit 32, and the
core-sched execute path never goes through class dequeue anyway -
set_next_task_scx() calls ops_dequeue() with the flag directly. The test was
live when the SCX_DEQ_SCHED_CHANGE computation sat in ops_dequeue() and
became dead when 03f5304aad ("sched_ext: Pass full dequeue flags to
ops.quiescent()") moved the computation here. Drop it.
