net: ethernet: ec_bhf: Fix dma_free_coherent() dma handle
[ Upstream commit ffe68c3766997d82e9ccaf1cdbd47eba269c4aa2 ]
dma_free_coherent() in error path takes priv->rx_buf.alloc_len as
the dma handle. This would lead to improper unmapping of the buffer.
Change the dma handle to priv->rx_buf.alloc_phys.
Fixes: 6af55ff52b02 ("Driver for Beckhoff CX5020 EtherCAT master module.")
