cfg80211: fix memory leak of wiphy device name
commit4f488fbca2
upstream. In wiphy_new_nm(), if an error occurs after dev_set_name() and device_initialize() have already been called, it's necessary to call put_device() (via wiphy_free()) to avoid a memory leak. Reported-by: syzbot+7fddca22578bc67c3fe4@syzkaller.appspotmail.com Fixes:1f87f7d3a3
