iwlwifi: correct 6000 EEPROM regulatory address

For 6000 series, the 2.4G HT40 band regulatory settings address in EEPROM was off by 2. Before the fix, you'll see this in dmesg: [79535.788877] ieee80211 phy8: U iwl_mod_ht40_chan_info HT40 Ch. 7 [2.4GHz] WIDE (0x61 0dBm): Ad-Hoc not supported [79535.788880] ieee80211 phy8: U iwl_mod_ht40_chan_info HT40 Ch. 11 [2.4GHz] WIDE (0x61 0dBm): Ad-Hoc not supported And after the fix: [91132.688706] ieee80211 phy14: U iwl_mod_ht40_chan_info HT40 Ch. 7 [2.4GHz] IBSS ACTIVE WIDE (0x6f 0dBm): Ad-Hoc supported [91132.688709] ieee80211 phy14: U iwl_mod_ht40_chan_info HT40 Ch. 11 [2.4GHz] IBSS ACTIVE WIDE (0x6f 0dBm): Ad-Hoc supported Signed-off-by: Shanyu Zhao <shanyu.zhao@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com>
