procfs: Don't cache a pid in the root inode.
Now that we have s_fs_info pointing to our pid namespace the original reason for the proc root inode having a struct pid is gone. Caching a pid in the root inode has led to some complicated code. Now that we don't need the struct pid, just remove it. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com>
