lavapipe: fix fencing when submitting multiple cmdbufs

Browse Source 
a fence applies to all the submitted cmdbufs, so it's necessary to do
the flush which creates the user fence after all the cmdbufs have been
processed in order to avoid creating a fence that only applies to the
first cmdbuf

Fixes: b38879f8c5 ("vallium: initial import of the vulkan frontend")
