Changeset f94e76ba in rtems

Fix after this report from Peter Pointner <pr@…>:

Problem: a posix thread which is created by

pthread_attr_init(&tattr);
pthread_attr_setinheritsched(&tattr, PTHREAD_EXPLICIT_SCHED);
pthread_attr_setschedpolicy(&tattr, SCHED_RR);
pthread_create(&th, &tattr, func, arg);

has a first timeslice of 2^{32 ticks (changing a running thread to
SCHED_RR id ok).}

I use RTEMS-4.0.0. I am not sure if the problem exists in the current CVS
head revision. If it's not fixed, the patch at the end should do it.
