netfilter: x_tables: use correct integer types
Sparse complains because __be32 and u32 are mixed without
conversions. Use the correct types, no code changes.
Furthermore, xt_DSCP generates a bit truncation warning:
"cast truncates bits from constant value (ffffff03 becomes 3)"
The truncation is fine (and wanted). Add a private definition and use that
instead.
objdiff shows no changes.
