Subject: [PATCH net-next 4/8] iavf: Remove redundant pci_enable_pcie_error_reporting()

From: Bjorn Helgaas <bhelgaas@...gle.com>

pci_enable_pcie_error_reporting() enables the device to send ERR_*
Messages.  Since f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is
native"), the PCI core does this for all devices during enumeration.

Remove the redundant pci_enable_pcie_error_reporting() call from the
driver.  Also remove the corresponding pci_disable_pcie_error_reporting()
from the driver .remove() path.

Note that this doesn't control interrupt generation by the Root Port; that
is controlled by the AER Root Error Command register, which is managed by
the AER service driver.
