Subject: split up ->kill_sb
Hi Al and Christian,
this series splits ->kill_sb into separate ->shutdown_sb and ->free_sb
methods and then calls generic_shutdown_super from common code to clean
up the file system shutdown interface.
As a first step towards that it moves allocating and freeing the
anonymous block device dev_t into common code. As every super_block must
have a valid s_dev it makes sense to just do that if the file system
didn't set one by itself, and we can also detect if one was assigned
easily when shutting down.
