xgene-v2: Fix a resource leak in the error handling path of 'xge_probe()'

[ 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.
