Fixed stale API calls to membrk API in gemmlike.

Details:
- Updated stale calls to the bli_membrk API within the 'gemmlike'
  sandbox. This API is now called bli_pba (packed block allocator).
  Ideally, this forgotten update would have been included as part of
  21911d6, which is when the branch where the membrk->pba changes was
  introduced was merged into 'master'.
- Comment updates.
