ipv4: dst_entry leak in ip_send_unicast_reply()

Browse source

commit 4062090e3e upstream.

ip_setup_cork() called inside ip_append_data() steals dst entry from rt to cork
and in case errors in __ip_append_data() nobody frees stolen dst entry

Fixes: 2e77d89b2f ("net: avoid a pair of dst_hold()/dst_release() in ip_append_data()")
