CVS commit: src/sys/kern

["Maxime Villard" <maxv%netbsd.org@localhost>]

Module Name:    src
Committed By:   maxv
Date:           Mon Oct 14 16:27:04 UTC 2019

Modified Files:
        src/sys/kern: uipc_socket.c

Log Message:
Add a check before the memcpy. memcpy is defined to never take NULL as
second argument, and the compiler is free to perform optimizations knowing
that this argument is never NULL.

In this particular case, it was harmless. But still good to fix.
