James Smart 787d0580ca scsi: lpfc: Zero SLI4 fcp_cmnd buffer's fcpCntl0 field
It's possible that the fcpCntl0 reserved field is allocated non-zero.

For certain target storage arrays this could cause problems expecting
reserved fields to be all zero.

SLI3 path already allocates fcp_cmnd buffer with dma_pool_zalloc() in
lpfc_new_scsi_buf_s3.  The fcpCntl0 field itself is never proactively set
throughout the SCSI I/O path.  Thus, we only change the SLI4 fcp_cmnd
buffer allocation to dma_pool_zalloc.
