[PATCH 4.14 10/23] xgene-v2: Fix a resource leak in the error handling path of xge_probe()

[Greg Kroah-Hartman]

From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit 5ed74b03eb4d08f5dd281dcb5f1c9bb92b363a8d ]

A successful 'xge_mdio_config()' call should be balanced by a corresponding
'xge_mdio_remove()' call in the error handling path of the probe, as
already done in the remove function.

Update the error handling path accordingly.

Fixes: ea8ab16ab225 ("drivers: net: xgene-v2: Add MDIO support")
