scsi: core: Fix scsi_device_max_queue_depth()

The comment above scsi_device_max_queue_depth() and also the description of
commit ca4453213951 ("scsi: core: Make sure sdev->queue_depth is <=
max(shost->can_queue, 1024)") contradict the implementation of the function
scsi_device_max_queue_depth(). Additionally, the maximum queue depth of a
SCSI LUN never exceeds host->can_queue. Fix scsi_device_max_queue_depth()
by changing max_t() into min_t().
