Fix backwards compatibility mode for svn log --limit.

* subversion/libsvn_ra_dav/log.c
  (log_baton): add a limit_compat_bailout parameter that tells us when
   we can safely ignore an error while parsing a response.
  (log_end_element): set lb->limit_compat_bailout to TRUE when we are
   bailing out of parsing log messages.
  (svn_ra_dav__get_log): initialize lb.limit_compat_bailout, check for
   limit_compat_bailout before we return an error.
