[Qemu-devel] [PATCH] test qgraph.c: Fix segs due to out of scope default |

From: "Dr. David Alan Gilbert" <address@hidden>
The test uses the trick:
if (!opts) {
opts = &(QOSGraph...Options) { };
}
in a couple of places, however the temporary created
by the &() {} goes out of scope at the bottom of the if,
and results in a seg or assert when opts-> fields are
used (on fedora 30's gcc 9).
Fixes: fc281c802022cb3a73a5
