[PATCH 0/2] ALSA: xen-front: Fix event channel stream lifetime bugs

[Cássio Gabriel <cassiogabrielcontato@xxxxxxxxx>]

Fix two related event-channel issues in the Xen ALSA frontend.

The first patch resets the event channel's expected incoming event
id when a stream is cleared, and drops stale queued events from
the previous stream instance.

The second patch keeps the request channel connected from .open(),
where it is needed for hw-rule queries and stream open requests,
but delays the event channel until after a successful .prepare().
This prevents current-position events from reaching the ALSA position
handler before runtime buffer and period geometry are valid.
