virgl: flush cmd buffer when flushing frontbuffer 

When a resource is multisampled, we usually submit a multisampling
resolving blit before we present it or use it in some other way, but
currently we don't always flush the cmd buffer before flushing the
frontbuffer, this commit fixes that.

Fixes piglit's glx/glx-copy-sub-buffer MSAA cases on vtest, in
conjunction with other commits of this series.
