nfp: debug dump - decrease endian conversions

Browse Source 
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.
