alx: Fix an error handling path in 'alx_probe()'

BugLink: https://bugs.launchpad.net/bugs/1934179
[ Upstream commit 33e381448cf7a05d76ac0b47d4a6531ecd0e5c53 ]

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.
