scsi: iscsi: Fix redundant response for ISCSI_UEVENT_GET_HOST_STATS request

Browse Source 
[ Upstream commit 63ca02221c ]

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.
