Fix a memory leak in scsi_host_dev_release()
Avoid that kmemleak reports the following memory leak if a
SCSI LLD calls scsi_host_alloc() and scsi_host_put() but neither
scsi_host_add() nor scsi_host_remove(). The following shell
command triggers that scenario:
for ((i=0; i<2; i++)); do
srp_daemon -oac |
while read line; do
echo $line >/sys/class/infiniband_srp/srp-mlx4_0-1/add_target
done
done
unreferenced object 0xffff88021b24a220 (size 8):
comm "srp_daemon", pid 56421, jiffies 4295006762 (age 4240.750s)
hex dump (first 8 bytes):
