[PATCH 01/10] block: Move bdev_unhash_inode() after invalidate_partition()

[Jan Kara]

Move bdev_unhash_inode() after invalidate_partition() as
invalidate_partition() looks up bdev and will unnecessarily recreate it
if bdev_unhash_inode() destroyed it. Also use part_devt() when calling
bdev_unhash_inode() instead of manually creating the device number.
