Subject: chardev: fix "info chardev" output
X-Git-Tag: qemu-xen-4.4.0-rc1~6^2~355^2

chardev: fix "info chardev" output

Fill unset CharDriverState->filename with the backend name, so
'info chardev' will return at least the chardev type.  Don't
touch it in case the chardev init function filled it already,
like the socket+pty chardevs do for example.
