dump_wiphy_parse only assigns filter_wiphy if one of the supported

Actually sent a patch for this issue a little earlier. I should have
Cc'ed you explicitly, I guess.
Whoops. I saw your regression report and didn't look to see if you
fixed it :)
Looking at your patch, I'm worried that
- int filter_wiphy = -1;
+ int filter_wiphy;
might still break things, since Johannes used:
if (!cb->args[2]) {
...
} else if (cb->args[2] > 0) {
filter_wiphy = cb->args[2] - 1;
}
So for unfiltered dumps, filter_wiphy would not be initialized properly
for the second & onward call of nl80211_dump_interface. Right?
