qcacmn: Flush TxLookupQueue for WMI_CONTROL_SVC during htc_stop

TX comletion for WMI_FORCE_FW_HANG_CMDID would come after
TARGET_STATUS_RESET is set. In such a senario, there would
be memory leak.

Flush TxLookupQueue for WMI_CONTROL_SVC during htc_stop.
Since netbuf is freed in ISR, just free HTC frame here.
