You need to use the *length* of the value as well.
(requests->requestvb->val_len)

You cannot assume that string values are null-terminated.
Try

    strncpy ( set_val, requests->requestvb->val.string,
                    requests->requestvb->val_len);
    set_val[ requests->requestvb->val_len ] = 0;


Also, this code appears to be assuming that there will
only ever be one varbind in a SET request.
The processing should be wrapped within a loop:

   for  (  req = requests;  req;   req = req->next )

and then take the value from  'req->requestvb->val'
instead.
