dmaengine: sun6i: fix the uninitialized value for v_lli

Browse source 
dma_pool_alloc does not initialize the value of the newly allocated
block for the v_lli, and the uninitilize value make the tests failed
which is on pine64 with dmatest.
we can fix it just change the "|=" to "=" for the v_lli->cfg.
