    callout: ddb: resolve symbol of callout function
    
    In the ddb show callout function try to resolve the symbol of the
    callout function to improve debugging.  In my case I went through
    various callouts from show ktr to check what they were and this saved
    me opening lldb/gdb next to it (and still having the old kernel as
    the panic to debug was upon reboot).
