netdevsim: Use dscp_t in struct nsim_fib4_rt

Browse Source 
Use the new dscp_t type to replace the tos field of struct
nsim_fib4_rt. This ensures ECN bits are ignored and makes it compatible
with the dscp fields of struct fib_entry_notifier_info and struct
fib_rt_info.

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