From: Xiang Chen <chenxian...@hisilicon.com>
Variable dif in function sd_setup_read_write_cmnd() is the return value
of function scsi_host_dif_capable() which returns dif capability of disks.
If define it as bool, even for the disks which support DIF3, the function
still return dif=1, which causes IO error. So define variable dif as
unsigned int instead of bool.
