nv50: access only the available amount of textures
The textures array is defined as a number of PIPE_MAX_SAMPLERS per shader stage.
Currently nv50 driver handles only 3 shader stages, thus we wreck chaos when
accessing array-out-of-bounds.
Fixes a segfault in piglit/bin/arb_texture_buffer_object-data-sync -fbo -auto
