KP Singh ff448dfd59 bpf: Implement bpf_local_storage for inodes 
[upstream commit 8ea636848aca35b9f97c5b5dee30225cf2dd0fe6]

Similar to bpf_local_storage for sockets, add local storage for inodes.
The life-cycle of storage is managed with the life-cycle of the inode.
i.e. the storage is destroyed along with the owning inode.

The BPF LSM allocates an __rcu pointer to the bpf_local_storage in the
security blob which are now stackable and can co-exist with other LSMs.
