    renderer/native: add missing eglTerminate in EGLDevice error path
    
    Currently the EGLDevice code gets the display and calls eglInitialize.
    As a follow-up it checks the required EGL extensions - technically it
    could check the EGL device extensions earlier.
    
    In either case, eglTerminate is missing. Thus the connection to the
    display was still bound.
    
    This was highlighted with Mesa commit d6edccee8da ("egl: add
    EGL_platform_device support") + amdgpu.
    
    In that case, since the eglTerminate is missing, we end up reusing the
    underlying amdgpu_device due to some caching in libdrm_amdgpu. The
    latter in itself being a good solution since it allows buffer sharing
    across primary and render node of the same device.
    
    Note: we should really get this in branches all the way back to 3.30.
