Subject: [PATCH] ipmi_si: use smi_num for init_name

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.
