Subject: [PATCH] sd-dhcp-server: clear buffer before receive
I do not think this is necessary, but all other places in
libsystemd-network we clear buffer before receive. Without this,
Coverity warns about use-of-uninitialized-values.
Let's silence Coverity.
Closes CID#1469721.
(cherry picked from commit 40f9fa0af4c3094d93e833e62f7e301cd453da62)
