null_blk: move unregister_blkdev() after destroying dev in null_exit()

Browse source

In null_exit(), unregister_blkdev() is called before the null_blk instances
are destroyed, which is inconsistent with the cleanup order in null_init().
Move it after null_destroy_dev() so that teardown happens in the reverse
order of initialization.

No functional change intended.
