iavf: Fix an error handling path in 'iavf_probe()'

[ Upstream commit af30cbd2f4d6d66a9b6094e0aa32420bc8b20e08 ]

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.
