bug report: ath6kl: use after free

Hi Vipin,

There is a use after free bug in ar6000_ioctl_set_channelParams(). I'm not sure how to fix it.

drivers/staging/ath6kl/os/linux/ioctl.c +374
ar6000_ioctl_set_channelParams(51) warn: 'cmdp' was already freed.
370 if (cmd.numChannels > 1) {

   371          kfree(cmdp);
                      ^^^^
	freed here.

372 }
373

   374      ar->ap_wmode = cmdp->phyMode;
                           ^^^^^^
	dereferenced here.
