    ms/sched: Remove stale PF_MUTEX_TESTER bit
    
    The RTMUTEX tester was removed long ago but the PF bit stayed
    around. Remove it and free up the space.

    (cherry picked from ms commit 15917dc02841862840efcbfe1da0830f88078b5c)
    
    We've added vz specific flag which intersects with old mainstream's one,
    so let's drop the mainstream's flag, it's not used anyway and has been
    already dropped in modern ms kernel.
