[PATCH 37/77] net/virtio: Fix failover_replug_primary() return value regression

[Michael Roth]

From: Markus Armbruster <armbru@redhat.com>

Commit 150ab54aa6 "net/virtio: fix re-plugging of primary device"
fixed failover_replug_primary() to return false on failure.  Commit
5a0948d36c "net/virtio: Fix failover error handling crash bugs" broke
it again for hotplug_handler_plug() failure.  Unbreak it.

Commit 5a0948d36c4cbc1c5534afac6fee99de55245d12
