Subject: [PATCH] alx: Fix an error handling path in 'alx_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: ab69bde6b2e9 ("alx: add a simple AR816x/AR817x device driver")
