bnxt_en: Add tx_resets ring counter
Add a new tx_resets ring counter. This counter will be saved as
tx_total_resets across any reset. Since we currently do a full reset
in bnxt_sched_reset_txr(), the per ring counter will always be cleared
during reset. Only the tx_total_resets count will be meaningful and we
only display this under ethtool -S.
