Use umtx_copyin_umtx_time32() in __umtx_op_lock_umutex_compat32().

Summary

This appears to have been a typo. This had no impact because the
underlying implementation returns EINTR if timeout is non-NULL.

The change is fine, but I do not understand the comment. I suspect that often invalid clock_id is read and ulock compat32 fails.

You are correct. I misread do_lock_umutex.
