glsl: explicitly zero out padding to gl_shader_variable bitfield
Otherwise, the padding bits remain undefined, which leads to valgrind errors when storing the gl_shader_variable in the disk cache. v2: use rzalloc instead of an explicit padding member variable Reviewed-by: Marek Olšák <[email protected]> Reviewed-by: Timothy Arceri <[email protected]>
