scsi: qedf: Use 'dma_zalloc_coherent' to reduce code verbosity.
Replace some 'dma_alloc_coherent+memset' by some quivalent 'dma_zalloc_coherent' in order to reduce code verbosity Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Acked-by: Chad Dupuis <chad.dupuis@cavium.com> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
