commit f570d33b02d824e2a3f676f718c4692572f45333
Author: Matt Caswell <matt at openssl.org>

    Only call dtls1_start_timer() once
    
    The function dtls1_handle_timeout() calls dtls1_double_timeout() which
    was calling dtls1_start_timer(). However dtls1_start_timer() is also
    called directly by dtls1_handle_timeout(). We only need to start the timer
    once.
    
    Fixes #15561
