Subject: [PATCH] qom: Fix crash with qom-list and link properties
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Commit 9561fda8d90e176bef598ba87c42a1bd6ad03ef7 changed the type of
'opaque' for link properties, but missed updating this call site.
Reproducer:

./x86_64-softmmu/qemu-system-x86_64 -qmp unix:./qmp.sock,server &
./scripts/qmp/qmp-shell ./qmp.sock
(QEMU) qom-list path=//machine/i440fx/pci.0/child[2]
