Subject: [PATCH] ethernet: atheros: fix a memleak in atl1e_setup_ring_resources
In the error handling of 'offset > adapter->ring_size', the
tx_ring->tx_buffer allocated by kzalloc should be freed,
instead of 'goto failed' instantly.
Fixes: a6a5325239c2 ("atl1e: Atheros L1E Gigabit Ethernet driver")
