Drop the ternary operator for calculating ssid display length in list_scan()

[sevan]

Summary

Regardless if a verbose scan is required or not, the answer is always 32 for now
and should IEEE80211_NWID_LEN be raised from the value of 32 we'd still want to
display the full SSID name by default as that is a common use case for invoking
a scan (finding out what networks are available).

You're right that the ternary operator is now redundant. I wonder if it wouldn't be better to just get rid of ssidmax and use IEEE80211_NWID_LEN everywhere in its place:

As @kristof suggested.
