Follow-up to r1033547: track mod_dav API change.

In r882274, the mod_dav API changed in two ways: the signatures of
dav_new_error() and dav_new_error_tag() changed, and 'struct dav_error'
changed its errno number member into an apr_status_t.  r1033547 tracked
the former change but not the latter.

* subversion/mod_dav_svn/util.c
  (dav_svn__log_err): Track the change to 'struct dav_error'.
