vhost: revert workaround MQ fails to startup

Browse Source 
This reverts commit 04d8122796 ("vhost: workaround MQ fails to
startup").

As agreed when this workaround was introduced, it can be reverted
as Qemu v2.10 that fixes the issue is now out.

The reply-ack feature is required for vhost-user IOMMU support.
