btrfs: simpilify btrfs_subvol_inherit_props
Author: Jeff Mahoney <jeffm@suse.com>
We just need a superblock, but we look it up using two different
roots depending on the call site. Let's just use a superblock
pointer initialized at the outset.
This is mostly for Coccinelle not to choke on my root push up set.
