From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>
[ Upstream commit edab74e9cb1d073c70add0f9b75e17aebf0598ff ]
Update the size used in 'dma_free_coherent()' in order to match the one
used in the corresponding 'dma_alloc_coherent()'.
Fixes: 369a782af0f1 ("net: sgi: ioc3-eth: ensure tx ring is 16k aligned.")
