That's because the fix in commit 3fec323339a4 ("drivers: perf: Fix panic in riscv SBI mmap support") was wrong since there is no need to broadcast to other cpus when starting a counter, that's only needed in mmap when the counters could have already been started on other cpus, so simply remove this broadcast.
