[libvirt] [PATCH] vz: fix SDK event dispatching

[nshirokovskiy at virtuozzo.com]

From: Nikolay Shirokovskiy <nshirokovskiy at virtuozzo.com>

Current version of SDK event dispatcing is incorrect. For most VM events (add,
delete etc) issuer type is PIE_DISPATCHER. Actually analyzing issuer type
doesn't have any benifints so this patch get rid of it. All dispatching is done
only on event type.
