QEMU aborts when default RAM backend should be used (i.e. no
explicit '-machine memory-backend=' specified) but user
has created an object which 'id' equals to default RAM backend
name used by board.
$QEMU -machine pc \
-object memory-backend-ram,id=pc.ram,size=4294967296
Actual results:
QEMU 7.2.0 monitor - type 'help' for more information
(qemu) Unexpected error in object_property_try_add() at ../qom/object.c:1239:
qemu-kvm: attempt to add duplicate property 'pc.ram' to object (type 'container')
Aborted (core dumped)
Instead of abort, check for the conflicting 'id' and exit with
an error, suggesting how to remedy the issue.
