We are returning the wrong count for ETH_SS_STATS in get_sset_count()
when XDP or TCs are enabled. In a recent commit, we got rid of
irrelevant counters when the ring is RX only or TX only, but we
did not make the proper adjustments for the count. As a result,
when we have XDP or TCs enabled, we are returning an excess count
because some of the rings are TX only. This causes ethtool -S to
display extra counters with no counter names.
Fix bnxt_get_num_ring_stats() by not assuming that all rings will
always have RX and TX counters in combined mode.
Fixes: 125592fbf467 ("bnxt_en: show only relevant ethtool stats for a TX or RX
ring")
