Btrfs: set FMODE_EXCL in btrfs_device->mode
This fixes a bug introduced in d4d77629, where the device added online (and therefore initialized via btrfs_init_new_device()) would be left with the positive bdev->bd_holders after unmount. Since d4d77629 we no longer OR FMODE_EXCL explicitly on blkdev_put(), set it in btrfs_device->mode.
