Subject: memcg: remove extra newlines from memcg oom kill log

Commit e61734c55c24 ("cgroup: remove cgroup->name") added two extra
newlines to memcg oom kill log messages.  This makes dmesg hard to read
and parse.  The issue affects 3.15+.

Example:
  Task in /t                          <<< extra #1
   killed as a result of limit of /t
                                      <<< extra #2
  memory: usage 102400kB, limit 102400kB, failcnt 274712

Remove the extra newlines from memcg oom kill messages, so the messages
look like:
  Task in /t killed as a result of limit of /t
  memory: usage 102400kB, limit 102400kB, failcnt 240649
