i965: revert part of commit 4f4907d69f9020ce17aef21b6431d2dd65e01982

The drm_intel_gem_bo_map_gtt() call that replaced dri_bo_map() is
producing errors like:

intel_bufmgr_gem.c:689: Error preparing buffer map 39 (vp_const_buffer): Invalid argument .

and returning NULL, causing a segfault in the memcpy().

Just reverting until we can get to the root issue...
