Arend van Spriel e1e1218032 wifi: cfg80211: fix memory leak in query_regdb_file()
[ Upstream commit 57b962e627 ]

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.
