Effectively undo r1532730 and remove the bogus "return SVN_NO_ERROR"
line that slipped in accidentally -- probably while going through
the code and commenting everything properly.

* subversion/libsvn_repos/config_pool.c
  (find_repos_config): remove early return statement and re-enable
                       remaining code
