2.6.39.3 nouveau_gart_manager_new() leaks memory

[Frank van Maarseveen]

/proc/slabinfo shows an anomaly on a 2.6.39.3 x86_64 system. After
running F14 + kde4 for a while it shows high kmalloc-192 numbers:

# name <active_objs> <num_objs> <objsize> <objperslab> <pagesperslab>...
kmalloc-192       735694 735723    264   31    2 : tunables    0    0    0 : slabdata  23733  23733      0

Digging in /sys/kernel/slab/kmalloc-192/alloc_calls one line stands out:

 701960 nouveau_gart_manager_new+0x5d/0xf0 age=24/7405655/87972315 pid=1-4920 cpus=0-3

There are 709907 allocations total and according to
/sys/kernel/slab/kmalloc-192/free_calls there are 52245 free
calls total.
