sched_ext: Check bpf_timer_start return values in scx_qmap
monitor_timerfn(), lowpri_timerfn() and round_robin_timerfn() ignore
bpf_timer_start()'s return value: a failed re-arm silently stops the
periodic heartbeat, starving every task parked in LOWPRI_DSQ (lowpri)
or freezing cid rotation (round-robin). Check the returns and raise
scx_bpf_error(), matching the init paths.
