Subject: [PATCH 28/28] usb-redir: Don't try to write to the chardev after a

 close event

Sicne we handle close async in a bh, do_write and thus write can get

called after receiving a close event. This patch adds a check to

the usb-redir write callback to not do a qemu_chr_write on a closed

chardev.
