Reset thread cookie upon exit
Once a thread cookie has been corrupted, we cannot use the existing
test facility to exit a thread on panics without resetting its cookie
such that it can exit without triggering additional panics. We only
do so for test threads that have the exit-on-panic flag set. If this
flag is set, we are also more lenient w.r.t. the thread state.
In thread_resched, the call to get_top_thread is moved past the first
call to thread_cookie_check. This is necessary to cleanly exit a test
thread with a corrupted cookie because thread_preempt might have put
said thread at the head of its run queue.
