That should happen in qmp_chardev_add(), so filename is set consistently
for every chardev no matter how it gets created.
Take care to not overwrite filename, some functions
(qmp_chardev_open_socket for example) do set chr->filename already.
Maybe it's better to put that into the individual qmp_chardev_open_*
functions anyway.
