Felix Fietkau 58bca02682 cfg80211: fix antenna gain handling
commit c4a9fafc77 upstream.

No driver initializes chan->max_antenna_gain to something sensible, and
the only place where it is being used right now is inside ath9k. This
leads to ath9k potentially using less tx power than it can use, which can
decrease performance/range in some rare cases.

Rather than going through every single driver, this patch initializes
chan->orig_mag in wiphy_register(), ignoring whatever value the driver
left in there. If a driver for some reason wishes to limit it independent
from regulatory rulesets, it can do so internally.
