diff of attempt to partially revert problem commit

Naive attempt to revert

My first attempt to revert the patch revealed to be the problem
above did not work.  (A diff of the changes is attached.)  The 
problem commit touched evergreen_cs.c and r600_cs.c, and since I
have Evergreen Juniper hardware I only reverted the code in
evergreen_cs.c.  The kernel built using this approach still
leaked memory.
