md/r5cache: move mddev_lock() out of r5c_journal_mode_set()

commit ff35f58e8f8eb520367879a0ccc6f2ec4b62b17b upstream.

r5c_journal_mode_set() is called by r5c_journal_mode_store() and
raid_ctr() in dm-raid. We don't need mddev_lock() when calling from
raid_ctr(). This patch fixes this by moves the mddev_lock() to
r5c_journal_mode_store().
