ch_ktls: do not send snd_una update to TCB in middle

commit e8a4155567b3c903f49cbf89b8017e9cc22c4fe4 upstream.

snd_una update should not be done when the same skb is being
sent out.chcr_short_record_handler() sends it again even
though SND_UNA update is already sent for the skb in
chcr_ktls_xmit(), which causes mismatch in un-acked
TCP seq number, later causes problem in sending out
complete record.
