Remove the matching of mac/mpls as a default selection. These are not
necessarily set by a TC rule (unlike the port). Previously a mac/mpls
field would exist in every match and be masked out if not used. This patch
has no impact on functionality but removes unnessary memory assignment in
the match cmsg.

Port matching is selected by default on every rule so remove check for it
and delete 'else' side of the statement. Remove nfp_flower_meta_one as now
it will not feature in the code. Rename nfp_flower_meta_two given that one
has been removed.
'Additional metadata' if statement can never be true so remove it as well.

Convert the requested dump level parameter to big-endian at the start of
nfp_net_dump_calculate_size() and nfp_net_dump_populate_buffer(), then
compare and assign it directly where needed in the traversal and prolog
code. This decreases the total number of conversions used.
