net: hns3: adjust hns3_uninit_phy()'s location in the hns3_client_uninit() 

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: c8a8045b2d ("net: hns3: Fix NULL deref when unloading driver")
