nouveau: pacify gcc on ILP32

Browse source 
The gcc we're using (and quite possibly newer ones) throws a really
stupid error:

   ../src/gallium/drivers/nouveau/nouveau_buffer.c:765:22: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
      buffer->address = (uint64_t)user_ptr;

Which... address is a uint64_t, and user_ptr is a void *, so this is
completely unambiguously safe to do. Apparently casting to uintptr_t
squelches this, so do that instead.
