qatomic_cxx11: fix fetchAndAdd*()

In qatomic_cxx11, the 'Type' is std::atomic<T>, whose fetch_add method,
used in fetchAndAdd*(), already does the right thing for T* with sizeof(T) > 1.
The code, however, applied 'AddScale' to the 'valueToAdd', thus becoming
incompatible with normal pointer arithmetics.

This is very apparent when one goes to the length of actually testing
qatomic_cxx11 with tst_QAtomicPointer (which is non-trivial, since the
-c++11 configure option currently doesn't have an effect on tests/auto).

To fix, remove the AddScale factor.
