Subject: [PATCH] netxen_nic: Fix an error handling path in 'netxen_nic_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: e87ad5539343 ("netxen: support pci error handlers")
