[PATCH] vl: Add opts to device opts list when using JSON syntax for -device

[MkfsSion]

When using JSON syntax for -device, -set option can not find device
specified in JSON by id field. The following commandline is an example:

$ qemu-system-x86_64 -device '{"id":"foo"}' -set device.foo.bar=1
qemu-system-x86_64: -set device.foo.bar=1: there is no device "foo" defined

The patch adds device opts to device opts list when a device opts get
parsed.
