Issue title: wrong tid in cta_launch with non power of two NT
 Issue body: using cta_launch with NT not being a power of two results in wrong tid values passed to the lambda. simple test case:

``` cpp
static const int NT = 96
mgpu38d1:d2b4:3d06:83e8:96a5:8c2:893d:aba5ta_launch<NT>([=] MGPU_DEVICE (const int tid, const int block) {
      printf("thread %d %d %d\n", threadIdx.x, tid, threadIdx.x & (NT - 1));
}, 1, ctx);
```

For NT = 32, 64 and 128 this works fine. However setting NT to any multiple of 32 should be valid, right?

 Comment 0: That's a good point. I should definitely change that. Started off only supporting powers of two because I wasn't sure if all the algorithms I wrote would work on those odd CTA sizes. But I should relax that restriction for cta_launch and transform etc, and static_assert inside non-supported functions if I need to. Will roll that fix out in the next update. Thx.
 Comment 1: Fixed in the 2.10 push. Let me know if you have problems with it.
 Comment 2: works fine now, thanks for the fix
