Murray McAllister 5ed7f4b5ec drm/vmwgfx: integer underflow in vmw_cmd_dx_set_shader() leading to an invalid read ...

If SVGA_3D_CMD_DX_SET_SHADER is called with a shader ID
of SVGA3D_INVALID_ID, and a shader type of
SVGA3D_SHADERTYPE_INVALID, the calculated binding.shader_slot
will be 4294967295, leading to an out-of-bounds read in vmw_binding_loc()
when the offset is calculated.
