curl_trace(): eliminate switch fallthrough

Our trace handler is called by curl with a curl_infotype
variable to interpret its data field. For most types we
print the data and then break out of the switch. But for
CURLINFO_TEXT, we print data and then fall through to the
"default" case, which does the exact same thing (nothing!)
that breaking out of the switch would.

This is probably a leftover from an early iteration of the
patch where the code after the switch _did_ do something
interesting that was unique to the non-text case arms.
But in its current form, this fallthrough is merely
confusing (and causes gcc's -Wimplicit-fallthrough to
complain).

Let's make CURLINFO_TEXT like the other case arms, and push
the default arm to the end where it's more obviously a
catch-all.
