sched_ext: Fix scx_bpf_reenqueue_local() silently reenqueuing nothing

Browse Source 
ffa7ae0724 ("sched_ext: Add reenq_flags plumbing to scx_bpf_dsq_reenq()")
introduced task_should_reenq() as a filter inside reenq_local(), requiring
SCX_REENQ_ANY to be set in order to match any task. scx_bpf_dsq_reenq()
handles this correctly by converting a bare reenq_flags=0 to SCX_REENQ_ANY,
but scx_bpf_reenqueue_local() was not updated and continued to call
reenq_local() with 0, causing it to silently reenqueue zero tasks.

Fix by passing SCX_REENQ_ANY directly.
