nvme-fabrics: fix I/O connect error handling

In nvmf_connect_io_queue(), if connect I/O command fails, we log the
error and continue for authentication. This overrides error captured
from __nvme_submit_sync_cmd(), causing wrong return value.

Add goto out_free_data after logging connect error to fix the issue.
