[PATCH] Documentation/robust-futex-API: count properly to 4

[Henrik Austad]

A strictly monotonically increasing sequence is normally used in
numbered lists as they provide an intuitive ordering of the elements.

However, in situations where race conditions can appear, this assumption
breaks down and you can end up with unpredictable results, leading to a
rather confusing list :-)

This changes the numbered list 1,2,2,2 to the more intuitive 1,2,3,4.

Introduces in 2eec9ad9 (lightweight robust futexes: docs)
