vhost: simplified timed event code

Browse Source 
Removed leftover code.

spdk_vhost_timed_event struct has been stripped from
spdk_event and timeout fields. The first one was not
required since vhost_timed_events are not reusable
anymore. The latter has been removed to prepare
vhost_timed_event struct to be expanded to generic
- also non-timing out - vhost_event struct.
