[SCSI] mvsas: remove mvs_slave_{alloc|configure}
libsas now handles: 1/ limiting ata scanning to lun0 2/ maximizing the queue_depth of sas devices (up to 256, mvsas only supports 64) 3/ changes to /sys/block/<sdX>/device/queue_depth for ata devices Acked-by: Xiangliang Yu <yuxiangl@marvell.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
