    htl: Fix sem_wait race between read and gsync_wait

    If the value changes between sem_wait's read and the gsync_wait call,
    the kernel will return KERN_INVALID_ARGUMENT, which we have to interpret
    as the value having already changed.

    This fixes applications (e.g. libgo) seeing sem_wait erroneously return
    KERN_INVALID_ARGUMENT.
