qemu-char: Check for missing backend name

Check if the backend option is missing before searching the backend
table. This fixes a NULL pointer dereference when QEMU is invoked with
the following invalid command-line:

$ qemu -chardev id=foo,path=/tmp/socket

Previously QEMU would segfault, now it produces this error message:

chardev: "foo" missing backend
