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
