5.4-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 63ca02221cc5aa0731fe2b0cc28158aaa4b84982 ]
The ISCSI_UEVENT_GET_HOST_STATS request is already handled in iscsi_get_host_stats(). This fix ensures that redundant responses are skipped in iscsi_if_rx().
- On success: send reply and stats from iscsi_get_host_stats() within if_recv_msg().
- On error: fall through.
