Subject: [PATCH 4.9 27/60] e1000e: Fix an error handling path in e1000_probe()

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

[ Upstream commit 4589075608420bc49fcef6e98279324bf2bb91ae ]

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.
