Subject: [PATCH net] sctp: remove temporary variable confirm from sctp_packet_transmit

Commit c86a773c7802 ("sctp: add dst_pending_confirm flag") introduced
a temporary variable "confirm" in sctp_packet_transmit.

But it broke the rule that longer lines should be above shorter ones.
Besides, this variable is not necessary, so this patch is to just
remove it and use tp->dst_pending_confirm directly.

Fixes: c86a773c7802 ("sctp: add dst_pending_confirm flag")
