scsi: iscsi: Fix redundant response for ISCSI_UEVENT_GET_HOST_STATS request
[ 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.
