NFC: pn533: Remove unused pn533_send_cmd_frame_asy
Remove obsolete send async api as it's no longer used. Remove global dev->in_frame as well, as each packet is kept is a seperate skb struct now, so that's not used anymore. Signed-off-by: Waldemar Rymarkiewicz <waldemar.rymarkiewicz@tieto.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
