[PATCH] IPMI: fix occasional oops on module unload

Olaf Kirch of SuSE tracked down a problem where module unloads of the IPMI
driver would occasionally result in Oopses.  He tracked that down to a
variable that wasn't always initialized properly in some situations.  This
patch initializes that variable.  Olaf sent a patch that kzalloc-ed the
data, but this structure is large enough that I would perfer to not do
that.  Thanks Olaf!
