[PATCH 4.19 043/125] scsi: iscsi: Do not put host in iscsi_set_flashnode_param()

[Greg Kroah-Hartman]

From: Jing Xiangfeng <jingxiangfeng@xxxxxxxxxx>

[ Upstream commit 68e12e5f61354eb42cfffbc20a693153fc39738e ]

If scsi_host_lookup() fails we will jump to put_host which may cause a
panic. Jump to exit_set_fnode instead.
