nvc0: add a note about MP counters on GF100/GF110
MP counters on GF100/GF110 (compute capability 2.0) are buggy because there is a context-switch problem that we need to fix. Results might be wrong sometimes, be careful! Signed-off-by: Samuel Pitoiset <samuel.pitoiset@gmail.com> Reviewed-by: Ilia Mirkin <imirkin@alum.mit.edu>
