Subject: net: hns3: adjust hns3_uninit_phy()'s location in the
 hns3_client_uninit()
Patch-mainline: v5.3-rc1
Git-commit: 0d2f68c7bcf4c7bbdd6f810f7b6e658f43d4461e
References: bsc#1104353 FATE#326415

hns3_uninit_phy() should be called before checking
HNS3_NIC_STATE_INITED flags, otherwise when this checking fails,
there is nobody to call hns3_uninit_phy().

Fixes: c8a8045b2d0a ("net: hns3: Fix NULL deref when unloading driver")
