tcp: do not set rtt_min to 1

commit 372022830b06d9980c7e8b41fa0a4081cff883b0 upstream.

There are some cases where rtt_us derives from deltas of jiffies,
instead of using usec timestamps.

Since we want to track minimal rtt, better to assume a delta of 0 jiffie
might be in fact be very close to 1 jiffie.

It is kind of sad jiffies_to_usecs(1) calls a function instead of simply
using a constant.
