wan/fsl_ucc_hdlc: Fix size used in dma_free_coherent()

Size used with 'dma_alloc_coherent()' and 'dma_free_coherent()' should be
consistent.
Here, the size of a pointer is used in dma_alloc... and the size of the
pointed structure is used in dma_free...

This has been spotted with coccinelle, using the following script:
////////////////////
@r@
expression x0, x1, y0, y1, z0, z1, t0, t1, ret;
@@

*   ret = dma_alloc_coherent(x0, y0, z0, t0);
    ...
*   dma_free_coherent(x1, y1, ret, t1);

@script:python@
y0 << r.y0;
y1 << r.y1;

@@
if y1.find(y0) == -1:
 print "WARNING: sizes look different:  '%s'   vs   '%s'" % (y0, y1)
