[PATCH AUTOSEL 4.14 33/44] net: cxgb3_main: Fix a resource leak in a error path in 'init_one()'

[ Upstream commit debea2cd3193ac868289e8893c3a719c265b0612 ]

A call to 'kfree_skb()' is missing in the error handling path of
'init_one()'.
This is already present in 'remove_one()' but is missing here.
