[Mesa-dev] [PATCH v4 5/9] egl: add going out of the loop when color_buffer is set.

[Gwan-gyeong Mun]

If color_buffer is set once, we don't need to set a same native buffer to
remained free slot of color_buffers. So we can go out of the loop when
color_buffer is set first.

Fixes from Emil's review
 - Add setting "updated" and bailing out when the color_buffer is set.[1]
