swr: Fixed an uncommon freed-memory access during state validation\n\nState validation is performed during clear and draw calls. Validation\nduring clear was still accessing vertex buffer state. When the currently\nset vertex buffers are client arrays, this could lead to accessing freed\nmemory. Such is the case with the VMD application.\n\nPreviously, vertex buffer validation depended on a dirty bit or the\ndraw info indicating an indexed draw. This required special handling for\nclears. But, vertex buffer validation still occurred which was unnecessary\nand wrong.\n\nNow, only minimal validation is performed during clear, deferring the\nremainder to the next draw. And, by setting the dirty bit in swr_draw_vbo\nfor indexed draws, vertex buffer validation is only dependent upon a\nsingle dirty bit.\n\nThis fixes a bug exposed by the VMD application when changing models.\n\nReviewed-By: George Kyriazis <george.kyria...@intel.com>
