Description

In the Linux kernel, the following vulnerability has been resolved:

wifi: mac80211: don't start a ROC while scanning

The ROC work can be pending when a scan starts (which requires ROC list to be empty, but that's possible), and then a new ROC can be added to the list and the work will pick it up.

Avoid starting that ROC if a scan made it between things, as otherwise we'll hit a warning later:
