wifi: cfg80211: fix potential requested_regd leak

Browse Source 
If a custom regdomain is registered by a driver by
calling regulatory_set_wiphy_regd() (the async one)
before the wiphy is registered, and then registration
fails or it's unregistered before the worker ran, we
leak the regdomain. Free it on wiphy free.
