vo_opengl: don't upload potentially uninitialized memory to GL buffer 

If the texture count is lower than 4, entries in va.textcoord[] will
remain uninitialized. While this is unlikely to be a problem (since
these values are unused on the shader side too), it's not nice and might
explain some things which have shown up in valgrind.

Fix by always initializing the whole thing.
