Fixed #31731 -- Removed unreachable code for resetting sequences of auto-created m2m tables in sequence_reset_sql().
Unreachable because f.remote_field.through is truthy for all m2m
fields.
Resetting sequences of auto-created m2m tables in sequence_reset_sql()
is also unnecessary:
- in sqlsequencereset since c39ec6dccb389fbb4047e44f5247e18bb76ae598
because auto-created tables are included in model_list,
- in loaddata because there is no it need to reset sequences for
models not loaded directly.
- in create_default_site() because it doesn't have m2m fields.
