Subject: [PATCH] Set the initial TRIM information as TRIMMED

From: Kyungmin Park <kyungmin.park@...sung.com>

Now trim information doesn't stored at disk so every boot time. it's cleared.
and do the trim all disk groups.
But assume that it's already trimmed at previous time so don't need to trim it again. So set the intial state as trimmed.
