Some constraints are imposed onto the ACC100 HARQ input size,
but that value is incorrectly aligned down when getting close to
max (Ncb-F) which is not required.
The wireless performance impact is negligeable but still causes a
few LLRs no to be combined at the very end of the circular buffer.

Applied to next-baseband/for-main.
