Subject: [PATCH 5.4 33/68] scsi: iscsi: Adjust iface sysfs attr detection

From: Baokun Li <libaokun1@...wei.com>

[ Upstream commit 4e28550829258f7dab97383acaa477bd724c0ff4 ]

ISCSI_NET_PARAM_IFACE_ENABLE belongs to enum iscsi_net_param instead of
iscsi_iface_param so move it to ISCSI_NET_PARAM. Otherwise, when we call
into the driver, we might not match and return that we don't want attr
visible in sysfs. Found in code review.
