Correctly initialize walkState values when calling walkStackFrames

[fengxue-IS]

After a thread's stackWalkState is used, we don't reset the fields to 0 but expects future code uses to set the parameters to the expected value before calling walkStackFrames. This change fixes walkWrapperImpl where userData1 is not properly set.

Fixes: #18696 Fixes: #18961

There was one CRIU test failure which seems unrelated to this change.
