[PATCH v2 4/4] qemu-storage-daemon: Remove QemuOpts from --object parser

[Kevin Wolf <kwolf@redhat.com>]

The command line parser for --object parses the input twice: Once into
QemuOpts just for detecting help options, and then again into a QDict
using the keyval parser for actually creating the object.

Now that the keyval parser can also detect help options, we can simplify
this and remove the QemuOpts part.
