gl: fix bug in _cairo_gl_surface_embedded_operand_init()

Browse source 
The operand->texture.surface should be set to right value, not
NULL. Otherwise, when doing _cairo_gl_surface_operand_init(),
the texture.surface in operand struct will also be NULL, which
is incorrect. This fix regression suite in 43 test cases(such
as source-clip) in cairo/test/.
