Subject: [PATCH] iavf: Fix an error handling path in 'iavf_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: 5eae00c57f5e ("i40evf: main driver core")
