[tor-commits] [tor/master] Don't let a bad IPv6 orport stop our IPv4 bandwidth test.

commit 2299b31f405e01abefa28924d86634b386949377

    Don't let a bad IPv6 orport stop our IPv4 bandwidth test.
    
    Specifically: do not close IPv4 bandwidth-testing circuits just
    because our IPv6 orport is unreachable.
    
    Attempted fix for #40068.
