Fix change to prevent cancel signal in unsafe places.
The bits tested to decide when to delay the return when switching
off async cancel mode were wrong. Fix that. Also close a race
condition in pthread_cancel where the bit indicating the cancellation
is unconditionally set even if the cancel type might have changed.
(cherry picked from commit 9437b427cec6266abd303983848549a5c4ba0d0a)
