Commit 3e41a317ae45 ("PCI/AER: Remove unused aer_error_resume()")
removed the resume err_handler from AER. Since no other port service
implements the callback, support for it can be removed from portdrv.
It can be revived later if need be, preferably by re-using the
pcie_port_device_iter() iterator.
