"cleanup osi_sleep.c to remove some additional races.  this patches
removes AFS_GLOBAL_SUNLOCK and just uses that case to handle both
smp and non smp cases.  osi_TimedSleep always sleeps atleast 1 hz.
(it also always sleeps interruptibly -- you might get some extra
loops but this is better than the load average running away)
sleep_on's are replaced with the more appropriate add_waitq/schedule
sequence.  getevent is called after addevent since there is no
danger of GLOCK dropping.  getevent/addevent isnt re-merged since
osi_Wakeup doesnt create entries in the event table."
