atm: idt77252: Remove call to memset after dma_alloc_coherent
In commit 518a2f1925c3 ("dma-mapping: zero memory returned from dma_alloc_*"), dma_alloc_coherent has already zeroed the memory. So memset is not needed. Signed-off-by: Fuqian Huang <huangfq.daxian@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
