virtio: Tell the user what went wrong when event_notifier_init failed
event_notifier_init() can fail in real life, for example when there are not enough open file handles available (EMFILE) when using a lot of devices. So instead of leaving the average user with a cryptic error number only, print out a proper error message with strerror() instead, so that the user has a better way to figure out what is going on and that using "ulimit -n" might help here for example.
