[SRU][Jammy:linux-intel-iotg][PATCH 0/1] wifi: iwlwifi: system hang after running stress-ng softlockup stressor while iwlwifi is connected to the station

[Jian Hui Lee]

BugLink: https://bugs.launchpad.net/bugs/2023176

[Impact]
system got hang after running stress-ng softlockup test while iwlwifi is connected to the station

[Test Plan]
1. compile test.
2. connect wifi (iwlwifi) to any station. (must do this)
3. execute the following command:
    $ sudo stress-ng --softlockup NUM_CPU_CORES --timeout 30
4. make sure the system still responses after testing

[Regression potential]
low. checking the txq for null is harmless.
