1. Don't segfault on unsupported mma->mma …

   triton-lang#4492 started causing an
   issue where chained MMAs on hopper would segfault with 8 warps. It seems
   that previously this was checked, but the check got removed in this PR
   and it's still unsupported.
   
   Adding back this check means these MMAs will have to go back to shared
   memory, but it's better than segfaulting until it's actually supported.
   
   Resolves openxla/xla#17356
