#8395: Valgrind error in lockfree::queue

Comment (by timblechmann):

 i will have to review this specific part carefully. the uninitialized part
 is related to the ABA prevention counter, simply initializing it may
 silent the valgrind warning, but introduce an ABA problem, so this patch
 might break the data structure in a very subtle way.

 this issue could possibly be considered as `false positive' and the better
 way to silence the warning, might be to initialize the memory region, not
 in the constructor, but when allocating memory from the OS.

 might take me some time to review all the code ...
