Agreed, the netlink related patch is not really broken, but it is
highlighting another issue that has been there with wpa_supplicant AP
mode from the beginning. It was just not showing up frequently enough to
get enough energy to fixing it. Your patch made it happen on every
P2P GO start, so this kind of changes ;-).

Instead of reverting the patch, I added yet another workaround for the
netlink download processing: commit
59d249255c5ea484ac2050f19ecbe84a7d9323f0.
