viced: Restore some previous log message language

viced: Restore some previous log message language

Before commit 6c41b1f740e16b5b9adfe9026630595be6f0699e, we logged
these three messages in the fileserver in different situations:

  CallPreamble: Couldn't get client.
  CallPreamble: Couldn't get CPS. Fail
  CallPreamble: couldn't reconnect to ptserver

After commits 6c41b1f740e16b5b9adfe9026630595be6f0699e and
0a5e878aa0a71c4dfaef1806744ed78bcc13b9f4, these messages were changed
to contain more useful information, but the language was also changed.
The messages now look like:

  Client host too busy while handling request from host %s:%d viceid %d fid %lu.%lu.%lu, failing request
  Cannot get CPS for client while handling request [...], failing request
  Cannot reconnect to ptserver while handling request [...], failing request

While the new messages are more informative, and (in my opinion)
better describe what is happening in those situations, they do look
very different from the old messages. This can break scripts that try
to parse these logs, but in general it is also not clear to
administrators that these messages still refer to the same events.

So instead, put these messages back the way they were. Still include
the extra information, of course, but revert the language to look more
like the old messages. Now we log:

  CallPreamble: Couldn't get client while handling request from host %s:%d viceid %d fid %lu.%lu.%lu, failing request
  CallPreamble: Couldn't get CPS while handling request [...], failing request
  CallPreamble: couldn't reconnect to ptserver while handling request [...], failing request

Thanks to Ben Kaduk for bringing this up.
