bnxt_en: add rx_filter_miss extended stats

rx_filter_miss counter is newly added to the rx_port_stats_ext
stats structure for newer chips.  Newer firmware will return the
structure size that includes this counter.  Add this entry to
the bnxt_port_stats_ext_arr array and the ethtool -S code will
pick up this counter if it is supported.
