net: sgi: ioc3-eth: Fix the size used in some 'dma_free_coherent()' calls

[ 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.")
