Subject: [PATCH] Tidy up left over smpnice code after changes introduced with
 CFS

1. The only place that RTPRIO_TO_LOAD_WEIGHT() is used is in the call to 
move_tasks() in the function active_load_balance() and its purpose here 
is just to make sure that the load to be moved is big enough to ensure 
that exactly one task is moved (if there's one available).  This can be 
accomplished by using ULONG_MAX instead and this allows 
RTPRIO_TO_LOAD_WEIGHT() to be deleted.

2. This, in turn, allows PRIO_TO_LOAD_WEIGHT() to be deleted.

3. This allows load_weight() to be deleted which allows 
TIME_SLICE_NICE_ZERO to be deleted along with the comment above it.
