makeWithOuterBlockInnerThreadStrategy: reuse fixThreadsBelow

Conceptually, this call performs the same operation as
the call to fixThreadsBelow in mapInnermostBandsToThreads,
so it makes sens to use the same function.
Note that fixThreadsBelow currently does essentially
the same as mapRemaining, but some thread specific code
will be added in an upcoming commit.
