drm/vmwgfx: Set dmabuf_size when vmw_dmabuf_init is successful
commit 91ba9f28a3de97761c2b5fd5df5d88421268e507 upstream. SOU primary plane prepare_fb hook depends upon dmabuf_size to pin up BO (and not call a new vmw_dmabuf_init) when a new fb size is same as current fb. This was changed in a recent commit which is causing page_flip to fail on VM with low display memory and multi-mon failure when cycle monitors from secondary display.
