CVE-2021-47194

If the userspace tools switch from NL80211IFTYPEP2PGO to NL80211IFTYPEADHOC via sendmsg(NL80211CMDSETINTERFACE), it does not call the cleanup cfg80211stopap(), this leads to the initialization of in-use data. For example, this path re-init the sdata->assignedchanctxlist while it is still an element of assignedvifs list, and makes that linked list corrupt.
