crypto: crypto4xx - Fix size used in dma_free_coherent()

The size used in 'dma_free_coherent()' looks un-initialized here.
ctx->sa_len is set a few lines below and is apparently not set by the
caller.
So use 'size' as in the corresponding 'dma_alloc_coherent()' a few lines
above.

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)
