net: net_cls: fd passed in SCM_RIGHTS datagram not set correctly
Commit 6a328d8c6f03501657ad580f6f98bf9a42583ff7 changed the update
logic for the socket but it does not update the SCM_RIGHTS update
as well. This patch is based on the net_prio fix commit
48a87cc26c13b68f6cce4e9d769fcb17a6b3e4b8
net: netprio: fd passed in SCM_RIGHTS datagram not set correctly
A socket fd passed in a SCM_RIGHTS datagram was not getting
updated with the new tasks cgrp prioidx. This leaves IO on
the socket tagged with the old tasks priority.
To fix this add a check in the scm recvmsg path to update the
sock cgrp prioidx with the new tasks value.
Let's apply the same fix for net_cls.
