block: Move bdev_unhash_inode() after invalidate_partition()
Move bdev_unhash_inode() after invalidate_partition() as invalidate_partition() looks up bdev and it cannot find the right bdev inode after bdev_unhash_inode() is called. Thus invalidate_partition() would not invalidate page cache of the previously used bdev. Also use part_devt() when calling bdev_unhash_inode() instead of manually creating the device number.
