Subject: [PATCH -next 1/3] scsi: Remove superfluous memset()

Fixes coccicheck warning:

./drivers/scsi/pmcraid.c:4709:3-21: WARNING: dma_alloc_coherent use in pinstance -> hrrq_start [ i ] already zeroes out memory,  so memset is not needed

dma_alloc_coherent use in status already zeroes out memory, so memset is not needed
