Subject: [PATCH 4.9 28/60] iavf: Fix an error handling path in iavf_probe()

From: Christophe JAILLET <christophe.jaillet@...adoo.fr>

[ Upstream commit af30cbd2f4d6d66a9b6094e0aa32420bc8b20e08 ]

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")
