dccp: Call security_inet_conn_request() after setting IPv4 addresses.
Initially, commit 4237c75 ("[MLSXFRM]: Auto-labeling of child
sockets") introduced security_inet_conn_request() in some functions
where reqsk is allocated. The hook is added just after the allocation,
so reqsk's IPv4 remote address was not initialised then.
However, SELinux/Smack started to read it in netlbl_req_setattr()
after the cited commits.
This bug was partially fixed by commit 284904a ("lsm: Relocate
the IPv4 security_inet_conn_request() hooks").
This patch fixes the last bug in DCCPv4.
Fixes: 389fb80 ("netlabel: Label incoming TCP connections correctly in SELinux")
Fixes: 07feee8 ("netlabel: Cleanup the Smack/NetLabel code to fix incoming TCP connections")
