Subject: [PATCH net-next] rxrpc: uninitialized variable in
 rxrpc_send_ack_packet()

The "pkt" was supposed to have been deleted in a previous patch.  It
leads to an uninitialized variable bug.

Fixes: 72f0c6fb0579 ("rxrpc: Allocate ACK records at proposal and queue for transmission")
Signed-off-by: Dan Carpenter <dan.carpenter@...cle.com>

Applies to net-next.
