cogl-winsys-egl-kms: Call swap notify handler even when pageflip ioctl fails

Browse Source 
This can happen when we dpms off the output or when login1 takes away
drm master status from our drm fd.  In either case, we need to call
the swap notify handler so that the compositor dosn't get stuck waiting
for that notification.  The compositor should stop repainting shortly in
both cases, as it's either going into dpms off mode or vt switching away.
