Drop some control interface debug print verbosity for send operations

These prints were at DEBUG level (-d), but they can be very frequent, so
drop them to MSGDUMP (-dd). This allows the prints to be suppressed in
common debugging cases while still leaving them easily enablable to
debug control interface issues without having to enable excessive
debugging.
