Subject: [PATCH 5.13 004/223] ixgbe: Fix an error handling path in ixgbe_probe()

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

[ Upstream commit dd2aefcd5e37989ae5f90afdae44bbbf3a2990da ]

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: 6fabd715e6d8 ("ixgbe: Implement PCIe AER support")
