nv50/nvc0: make transfers aware of PIPE_TRANSFER_MAP_DIRECTLY
If state tracker asked us to map resource directly and we can't do it (because of tiling), return NULL instead of doing full transfer - state tracker should handle it and fallback to some other method or repeat transfer without PIPE_TRANSFER_MAP_DIRECTLY. It greatly improves performance of xorg state tracker on nv50+, because its fallback (DFS/UTS) is much faster than full transfer.
