[XFS] move xfs_bmbt_killroot to common code
xfs_bmbt_killroot is a mostly generic implementation of moving from a real block based root to an inode based root. So move it to xfs_btree.c where it can use all the nice infrastructure there and make it pointer size agnostic The new name for it is xfs_btree_kill_iroot, following the old naming but making it clear we're dealing with the root in inode case here, and to avoid confusion with xfs_btree_new_root which is used for the not inode rooted case. I've also added a comment describing what it does and why it's named the way it is.
