Commit 1abf71e moved the creation of new_smi->dev to earlier in the init
sequence in order to provide infrastructure for log printing.
However, the init_name was created with a hard-coded value of zero. This
presents a problem in systems with more than one interface, producing a
call trace in dmesg.
To correct the problem, simply use smi_num instead of the hard-coded
value of zero.
Tested on a lenovo x3950.

There was actually a more general problem, the platform device wasn't
being set correctly, either, and there was a possible (though extremely
unlikely) race on smi_num. Add locks to clean up the race and use the
proper value for the platform device, too.
Tested on qemu in various configurations.
