mlxsw: Use dscp_t in struct mlxsw_sp_fib4_entry

Use the new dscp_t type to replace the tos field of struct
mlxsw_sp_fib4_entry. This ensures ECN bits are ignored and makes it
compatible with the dscp fields of fib_entry_notifier_info and
fib_rt_info.

This also allows sparse to flag potential incorrect uses of DSCP and
ECN bits.
