bnxt_en: Add ntuple matching flags to the bnxt_ntuple_filter structure.

aRFS filters match all 5 tuples.  User defined ntuple filters may
specify some of the tuples as wildcards.  To support that, we add the
ntuple_flags to the bnxt_ntuple_filter struct to specify which tuple
fields are to be matched.  The matching tuple fields will then be
passed to the firmware in bnxt_hwrm_cfa_ntuple_filter_alloc() to create
the proper filter.
