bnxt_en: Refactor filter insertion logic in bnxt_rx_flow_steer().
Add a new function bnxt_insert_ntp_filter() to insert the ntuple filter
into the hash table and other basic setup. We'll use this function
to insert a user defined filter from ethtool.
Also, export bnxt_lookup_ntp_filter_from_idx() and bnxt_get_ntp_filter_idx()
for similar purposes. All ntuple related functions are now no longer
compiled only for CONFIG_RFS_ACCEL
