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.
