Geert reported an invalid wait context[1] which is resulted by moving set_track_prepare() inside kmemleak_lock. This is not allowed because in RT mode, the spinlocks can be preempted but raw_spinlocks can not, so it is not allowd to acquire spinlocks while holding raw_spinlocks. The second patch fix same problem in kmemleak_update_trace().
