[dm-devel] [PATCH] multipath: fix multipath -l <devmap> without output

[Mauricio Faria de Oliveira]

Currently, the multipath -l <devmap> output is empty, and an error
is printed to syslog:

    # ./multipath -l mpatha
    #

    # echo $?
    1

    # tail /var/log/messages
    ...
    ... multipath: mpatha: can't get udev device

That's due to dev_type not being initialized, and incorrectly evaluated.
So, initialize it to DEV_NONE, which is verified/reset by get_dev_type().

Now there's actual output and no error in syslog:

    # ./multipath -l mpatha
    mpatha (3600a0b800011e95c000055d855167d1c) dm-0 IBM,1815      FAStT
    ...

    # echo $?
    0
