qdev_prop_set_netdev() fails when the property already has a non-null
value. Seems to go back to commit 30c367ed44
"qdev-properties-system.c: Allow vlan or netdev for -device, not
both", v1.7.0. Board code doesn't expect failure, and crashes:
$ qemu-system-x86_64 --nodefaults -nic user -netdev user,id=nic0 -global e1000.netdev=nic0
Unexpected error in error_set_from_qdev_prop_error() at /work/armbru/qemu/hw/core/qdev-properties.c:1101:
qemu-system-x86_64: Property 'e1000.netdev' doesn't take value '__org.qemu.nic0
'
Aborted (core dumped)
-device and device_add handle the failure:
$ qemu-system-x86_64 -nodefaults -netdev user,id=net0 -netdev user,id=net1 -device e1000,netdev=net0,netdev=net1

Error: Property 'e1000.netdev' doesn't take value 'net1'
Perhaps netdev property override could be made to work. Perhaps it
should. I'm not the right guy to figure this out. What I can do is
improve the error message a bit:
(qemu) device_add e1000,netdev=net1
Error: -global e1000.netdev=... conflicts with netdev=net1
