Since f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is native"), the PCI core does this for all devices during enumeration, so the driver doesn't need to do it itself. 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 only controls ERR_* Messages from the device. An ERR_* Message may cause the Root Port to generate an interrupt, depending on the AER Root Error Command register managed by the AER service driver. cd709aa90648 ("bnx2: Add PCI Advanced Error Reporting support.") added pci_enable_pcie_error_reporting() for all devices, and c239f279e571 ("bnx2: Enable AER on PCIE devices only") restricted it to BNX2_CHIP_5709 devices to avoid an error message when it failed on non-PCIe devices. The PCI core only enables PCIe error reporting on PCIe devices, which I assume means BNX2_CHIP_5709.
