[PATCH -next v2] scsi: sd: Fix unsigned expression compared with zero in sd_spinup_disk()

[Jiapeng Chong <jiapeng.chong@linux.alibaba.com>]

The return value from the call to scsi_execute_cmd() is int. However, the
return value is being assigned to an unsigned int variable 'the_result',
so making 'the_result' an int.

./drivers/scsi/sd.c:2333:6-16: WARNING: Unsigned expression compared with zero: the_result > 0.
