bnx2: Drop redundant pci_enable_pcie_error_reporting()

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, 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.
