Chen Zhongjin 833a9fd28c wifi: cfg80211: Fix not unregister reg_pdev when load_builtin_regdb_keys() fails 
In regulatory_init_db(), when it's going to return a error, reg_pdev
should be unregistered. When load_builtin_regdb_keys() fails it doesn't
do it and makes cfg80211 can't be reload with report:

sysfs: cannot create duplicate filename '/devices/platform/regulatory.0'
