connection: Fix broken log message when demarshalling short closure

Like the similar wl_log() message further into this function that was
fixed in commit 2fc248dc2c877d02694db40aad52180d71373d5a this should
be printing the sender_id saved earlier instead of *p.

Since p is incremented during the loop it would not only print an
incorrect object id, it could read past the end of the array.
