Subject: [PATCH] sd-dhcp: library code shouldn't log above LOG_DEBUG (#6001)

Let's downgrade the warning introduced by

955d99edc7991386a36e3d33924cc584931fde91 to debug, as we really

shouldn't log at more than debug level from library code.

(And while we are at it, print the MTU as the right (unsigned) type in

the format string.)

(cherry picked from commit 4dd53da97daf3f064149380b6ca9e53273d77d88)
