Alexei Starovoitov 64873307e8 bpf: Add a recursion check to prevent loops in bpf_timer
Do not schedule timer/wq operation on a cpu that is in irq_work
callback that is processing async_cmds queue.
Otherwise the following loop is possible:
bpf_timer_start() -> bpf_async_schedule_op() -> irq_work_queue().
irqrestore -> bpf_async_irq_worker() -> tracepoint -> bpf_timer_start().

Fixes: 1bfbc267ec ("bpf: Enable bpf_timer and bpf_wq in any context")
