Add safety check to sample mutex implementation

Due to inconsistent freeing strategy in pkparse.c the sample mutex
implementation in threading.c could lead to undefined behaviour by
destroying the same mutex several times.

This fix prevents mutexes from being destroyed several times in the
sample threading implementation.
