net: wan/fsl_ucc_hdlc: Fix dma_free_coherent() in uhdlc_memclean()

Browse source

[ Upstream commit 36bd7d5dee ]

The priv->rx_buffer and priv->tx_buffer are alloc'd together as
contiguous buffers in uhdlc_init() but freed as two buffers in
uhdlc_memclean().

Change the cleanup to only call dma_free_coherent() once on the whole
buffer.
