bnxt_en: Clear TPA flags when BNXT_FLAG_NO_AGG_RINGS is set.

Orabug: 25645429

Commit bdbd1eb59c56 ("bnxt_en: Handle no aggregation ring gracefully.")
introduced the BNXT_FLAG_NO_AGG_RINGS flag.  For consistency,
bnxt_set_tpa_flags() should also clear TPA flags when there are no
aggregation rings.
