fs: add a method to shut down the file system
Add a new ->shutdown super operation that can be used to tell the file
system to shut down, and call it from newly created holder ops when the
block device under a file system shuts down.
This only covers the main block device for "simple" file systems using
get_tree_bdev / mount_bdev. File systems their own get_tree method
or opening additional devices will need to set up their own
blk_holder_ops.
