Dexuan Cui 629e870ca4 scsi: core: Fix shost->cmd_per_lun calculation in scsi_add_host_with_dma() 
commit 50b6cb3516 upstream.

After commit ea2f0f7753 ("scsi: core: Cap scsi_host cmd_per_lun at
can_queue"), a 416-CPU VM running on Hyper-V hangs during boot because the
hv_storvsc driver sets scsi_driver.can_queue to an integer value that
exceeds SHRT_MAX, and hence scsi_add_host_with_dma() sets
shost->cmd_per_lun to a negative "short" value.

Use min_t(int, ...) to work around the issue.

Fixes: ea2f0f7753 ("scsi: core: Cap scsi_host cmd_per_lun at can_queue")
