ath: fix warning on usage of REGULATORY_CUSTOM_REG
ath wants to first apply the custom regd and only later
will it revert to not using it if an alpha2 regulatory
domain is found. Since the wireless core now enforces
usage of the REGULATORY_CUSTOM_REG strictly when
wiphy_apply_custom_regulatory() is used this makes
ath adhere to the expected behaviour but also updates
the wiphy after its done with the custom usage.
This fixes this warning:
[ 5.488733] ath: phy0: ASPM enabled: 0x43
[ 5.488735] ath: EEPROM regdomain: 0x0
[ 5.488736] ath: EEPROM indicates default country code should be used
[ 5.488736] ath: doing EEPROM country->regdmn map search
[ 5.488737] ath: country maps to regdmn code: 0x3a
[ 5.488737] ath: Country alpha2 being used: US
[ 5.488738] ath: Regpair used: 0x3a
[ 5.488738] ------------[ cut here ]------------
[ 5.488745] WARNING: CPU: 0 PID: 161 at
/home/sujith/dev/wireless-testing/net/wireless/reg.c:1361
wiphy_apply_custom_regulatory+0x17a/0x1b0 [cfg80211]()
[ 5.488746] wiphy should have REGULATORY_CUSTOM_REG
The wireless core can *later* lift this flag for us for when
using the regulatory_hint() to make this fix more generic.
