[Qemu-block] [PULL 20/21] block: Simplify append_open_options()

[Kevin Wolf]

From: Alberto Garcia <address@hidden>

This function returns a BDS's driver-specific options, excluding also
those from its children. Since we have just removed all children
options from bs->options there's no need to do this last step.

We allow references to children, though ("backing": "node0"), so those
we still have to remove.
