egl: restore surface type before linking config to its display

commit c2c2e9a (egl: implement EGL_KHR_gl_colorspace (v2)) leaves
_EGLConfig->SurfaceType set incorrectly before calling _eglLinkConfig(),
and the bad value is passed around to platform_android. set it to zero
as earlier.

v2: Set SurfaceType to 0, rather than surface_type (Suggested by Emil)
