The inode inactivation and CIL tracking percpu structures are per-xfs_mount structures. That means when we get a CPU dead notification, we need to then iterate all the per-cpu structure instances to process them. Rather than keeping linked lists of per-cpu structures in each subsystem, add a list of all xfs_mounts that the generic xfs_cpu_dead() function will iterate and call into each subsystem appropriately. This allows us to handle both per-mount and global XFS percpu state from xfs_cpu_dead(), and avoids the need to link subsystem structures that can be easily found from the xfs_mount into their own global lists.
