scsi: core: Fix incorrect usage of shost_for_each_device
shost_for_each_device(sdev, shost) \
for ((sdev) = __scsi_iterate_devices((shost), NULL); \
(sdev); \
(sdev) = __scsi_iterate_devices((shost), (sdev)))
When terminating shost_for_each_device() iteration with break or return,
scsi_device_put() should be used to prevent stale scsi device references
from being left behind.
