[tor-commits] [tor/release-0.3.1] hs: Cleanup logging statement in hs_intropoint.c

commit ff9c52966796bae56cd216697ba879c06f806034

    hs: Cleanup logging statement in hs_intropoint.c
    
    One log statement was a warning and has been forgotten. It is triggered for a
    successful attempt at introducting from a client.
    
    It has been reported here:
    https://lists.torproject.org/pipermail/tor-relays/2017-August/012689.html
    
    Three other log_warn() statement changed to protocol warning because they are
    errors that basically can come from the network and thus triggered by anyone.
    
    Fixes #23078.

+  o Minor bugfixes (logging, relay):
+    - Remove a log_warn() that has been forgotten when an introduction point
+      successfully established a hidden service prop224 circuit with a client.
+    - Three other log_warn() for an introduction point have been changed to
+      protocol warning because they can be failure from the network and are
+      not relevant to the operator. Fixes bug 23078; bugfix on
+      tor-0.3.0.1-alpha and tor-0.3.0.2-alpha.
