[PATCH] IPMI: Clean up the waiting message queue properly on unload

A wrong function was being used to free a list; this fixes the problem.
Otherwise, an oops at unload time was possible.  But not likely, since you
can't have any users when you unload the modules and it is very hard to get
messages into this queue without users.
