Fix early data bug with pause between EoED and CF

Browse Source 
If the server received EoED then SSL_read_early_data() will return
SSL_READ_EARLY_DATA_FINISH. However if the CF has not yet been processed
then SSL_is_init_finished() will still return 0. Therefore we should still
be able to write early data.

Fixes #3041
