When I test the 0.8.5 code with iscsi login/out, multipathd command
and multipath command concurrently, there is a multipathd coredump.
The stack is shown:
uxlsnrloop
->cli_list_devices
->show_devices
->snprint_devices
->find_path_by_dev
The reason is that devname is NULL in snprint_devices, then it will
be dereference. Here we check dev in find_path_by_dev.
