tty: n_tty: use time_is_before_jiffies() in n_tty_receive_overrun()
The jiffies tests in n_tty_receive_overrun() are simplified ratelimiting
(without locking). We could use struct ratelimit_state and the helpers,
but to me, it occurs to be too complex for this use case.
But the code currently tests both if the time passed (the first
time_after()) and if jiffies wrapped around (the second time_after()).
time_is_before_jiffies() takes care of both, provided overrun_time is
initialized at the allocation time.
So switch to time_is_before_jiffies(), the same what ratelimiting does.
