Hey all-
     I've put this patch together to fix up an oops in the olympic token 
ring driver.  The problem was orgionally reported as an oops which 
occurs on media disconnect.  The problem was that free_irq was being 
called from several places in the olympic interrupt handler, which 
triggered the subsequent oops.  This patch corrects that by removing the 
free_irq call from all the interrupt handler code paths, instead 
allowing the olympic_close to handle the free_irq on an interface down 
event.  The patch also cleans up some double free conditions on the 
receive ring buffer that arose due to this change.  Lastly the patch 
corrects a situation in which calling ifdown on an interface owned by 
the driver would hang the process in cases where the adaper needed to be 
reset to complete any operations, but never woke the wait queue which 
the olympic_close routine was waiting on.  This patch cleans that up.

Tested by me, on 2.4 and 2.6 with good, working results, and no more oopses.

Thanks!
Neil
