[SeaBIOS] Intermittent USB keyboard freeze

Additional verification check catches any address change (token address
not matching current device address).  That fixes the keyboard issue and
should also catch the obscure address change case.  And also the more
likely case of the address flipping back to zero due to a port reset.

cheers,
  Gerd
