tunnel: avoid race between shutdown and stats
wgTurnOff can block for a while, in which case, calling getStatistics
will use a stale handle and stale tunnel. Not only that, but wgGetConfig
might return null, in which case string.split throws.
java.lang.NullPointerException: Attempt to invoke virtual method
'java.lang.String[] java.lang.String.split(java.lang.String)' on a null
