ath9k_htc: Fix panic on FW download failure
Use the correct error condition exit in case firmware download
fails for some reason. Not doing so results in a panic:
usb 1-3: ath9k_htc: Transferred FW: ar9271.fw, size: 51280
usb 1-3: ath9k_htc: Firmware - ar9271.fw download failed
usb 1-3: ath9k_htc: Target is unresponsive
Failed to initialize the device
INFO: trying to register non-static key.
the code is fine but needs lockdep annotation.
turning off the locking correctness validator.
