Subject: [PATCH 4.4 21/57] netxen_nic: Fix an error handling path in 'netxen_nic_probe()'

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

[ Upstream commit 49a10c7b176295f8fafb338911cf028e97f65f4d ]

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: e87ad5539343 ("netxen: support pci error handlers")
