Subject: [PATCH] igb: Fix an error handling path in 'igb_probe()'

If an error occurs after a 'pci_enable_pcie_error_reporting()' call, it
must be undone by a corresponding 'pci_disable_pcie_error_reporting()'
call, as already done in the remove function.

Fixes: 40a914fa72ab ("igb: Add support for pci-e Advanced Error Reporting")
