[PATCH] ipmi: fix event queue limit 

The event handler mechanism in the IPMI driver had a limit on the number of
received events, but the counts were not being updated.  Update the counts
to impose a limit.  This is not a critical fix, as this function (the
sending of the events) has to be turned on by the user, anyway.  This
avoids problems if they forget to turn it back off.
