### Description / Steps to reproduce the issue
Hi all,
The performance tests using IPERF are failing after the PR #16231. This can
be easily replicated using the `sta_softap` defconfig on any of the following
targets: ESP32, ESP32S3, ESP32C3 and ESP32C6.
The test connects to WiFi hotspot succesfully, but fails when `iperf -c
` is called. It affects RISC-V and Xtensa devices, as shown above.
I have tracked the problem using `git bisect` and arrived at this point:
`sched/wqueue: Change dq to list.` (`9dbb9b49`)
# Steps to reproduce
Example using ESP32S3:
- Checkout to `9dbb9b49`
- `./tools/configure.sh esp32s3-devkit:sta_softap`
- Enable: `DEBUG_ASSERTIONS`, `SCHED_BACKTRACE`
- make and flash
- Connect to WiFi using `wapi essid`, `wapi psk` and `renew`
- Call `iperf -c `
# Error Log
```
