Fix handling of EGL_NONE as color space

Fix handling of EGL_NONE as color space

Color space of EGL_NONE was getting passed down and
driver threw EGL_BAD_ATTRIBUTE in response.
Issue was caused when changing the colorspace from nullptr
to EGL_NONE, missed a couple of places that needed to
test against EGL_NONE instead of nullptr.

Test: adb -d shell am start \
          -n com.drawelements.deqp/android.app.NativeActivity \
          -e cmdLine '"deqp --deqp-case=dEQP-EGL.functional.wide_color.* \
          --deqp-log-filename=/sdcard/dEQP-Log.qpa"'
