Subject: [PATCH] e1000e: Fix an error handling path in 'e1000_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: 111b9dc5c981 ("e1000e: add aer support")
