Subject: [PATCH] net: txgbe: Fix an error handling path in txgbe_probe()

A pci_enable_pcie_error_reporting() should be balanced by a corresponding
pci_disable_pcie_error_reporting() call in the error handling path, as
already done in the remove function.

Fixes: 3ce7547e5b71 ("net: txgbe: Add build support for txgbe")
