Cleanup the STATID_CONNECT and STATID_CONNECTFAIL stat counters

Browse source 
The STATID_CONNECT and STATID_CONNECTFAIL statistics were used
incorrectly. The STATID_CONNECT was incremented twice (once in
the *_connect_direct() and once in the callback) and STATID_CONNECTFAIL
would not be incremented at all if the failure happened in the callback.

Closes: #3452
(cherry picked from commit 59e1703b50dc4a5c52e3d6ae13bdd873a677b03f)
