gl: remove memory leak of orient_set

Summary:
The tex->pt->references is descreased by
evas_gl_common_texture_free -> pt_unref

if tex->references is 0

And tex->pt->texture is removed by
evas_gl_common_texture_free -> pt_unref -> glDeleteTextures

if tex->pt->references is 0

The evas_gl_common_texture_free decreases tex->references only
if tex->references is bigger than 0. There is no chance to decrease
tex->pt->references at this point.

So if orient_set increases both references of tex and tex->pt, then
the tex->pt->reference is not decreased till tex->references is 0.

So do not increase tex->pt->references in eng_orient_set.
