MDEV-9948 Failing assertion: new_state->key_version != ENCRYPTION_KEY_VERSION_INVALID in fil0crypt.cc

The test encryption.innodb-redo-nokeys did not actually test
recovery without valid keys, because due to the setting
innodb_encrypt_tables, InnoDB refused to start up at all,
without even attempting any crash recovery.

fil_ibd_load(): If the encryption key is not available,
refuse to load the file.
