kib d6cb692fee Do not leak curthread->inact_mtx when cancelling in pthread_cond_wait(3).
Leave robust-protected region before checking for cancellation by
calling _thr_testcancel().  Otherwise, if cancelling request was
pending, the cancel handler is called with the dandling inact_mtx,
which triggers an assert if any mutex operation is performed by the
handler.
