    Reset the rwstate before calling ASYNC_start_job()
    
    If an async job pauses while processing a TLS connection then the
    rwstate gets set to SSL_ASYNC_PAUSED. When resuming the job we should
    reset the rwstate back to SSL_NOTHING. In fact we can do this
    unconditionally since if we're about to call ASYNC_start_job() then either
    we are about to start the async job for the first time (in which case the
    rwstate should already by SSL_NOTHING), or we are restarting it after a
    pause (in which case reseting it to SSL_NOTHING is the correct action).
    
    Fixes #16809
