[PATCH 01/10] vhost: remove work arg from vhost_work_flush

[Mike Christie <michael.christie@oracle.com>]

vhost_work_flush doesn't do anything with the work arg. This patch drops
it and then renames vhost_work_flush to vhost_work_dev_flush to reflect
that the function flushes all the works in the dev and not just a
specific queue or work item.
