wifi: cfg80211: fix memory leak in query_regdb_file()
[ Upstream commit 57b962e ] In the function query_regdb_file() the alpha2 parameter is duplicated using kmemdup() and subsequently freed in regdb_fw_cb(). However, request_firmware_nowait() can fail without calling regdb_fw_cb() and thus leak memory.
