futex.2: Cut down discussion of FUTEX_REQUEUE; defer to FUTEX_CMP_REQUEUE
...
FUTEX_CMP_REQUEUE supercedes FUTEX_REQUEUE and provides a superset
of its functionality. There is need to duplicate any details in
the FUTEX_REQUEUE description, simple defer to the
FUTEX_CMP_REQUEUE and note the differences. This also guides the
reader to do the right thing: use FUTEX_CMP_REQUEUE rather than
FUTEX_REQUEUE.

This is a little more readable, and also helps avoid confusing
