Subject: [PATCH net-next] net: socket: Fix missing break in switch statement

Add missing break statement in order to prevent the code from falling
through to cases SIOCGSTAMP_NEW and SIOCGSTAMPNS_NEW.

This bug was found thanks to the ongoing efforts to enable
-Wimplicit-fallthrough.

Fixes: 0768e17073dc ("net: socket: implement 64-bit timestamps")
