net: hns3: Fixes the missing PCI iounmap for various legs 

We call pcim_iomap in hclge_pci_init, pcim_iounmap should be called
in error handle of hclge_init_ae_dev.

We call pcim_iomap in hclge_pci_init, but do not call pcim_iounmap in
hclge_pci_uninit. When we remove the hclge.ko and insert it again, a
problem that pci can not map will happen. pcim_iounmap need to be called
in hclge_pci_uninit.

Fixes: 46a3df9f97 ("net: hns3: Add HNS3 Acceleration Engine & Compatibility Layer Support")
