bnxt_en: Implement XDP RSS hash metadata extraction for V3_CMP
This adds another conditional when cmp_type is CMP_TYPE_RX_L2_V3_CMP for
drivers that support this completion format.
This re-uses bnxt_rss_ext_op to provide similar functionality. One
limitation is for L4 hash-types, protocol-specific bits can't be
determined.
