userns: Remove unnecessary cast to struct user_struct when copying cred->user.
In struct cred the user member is and has always been declared struct user_struct *user. At most a constant struct cred will have a constant pointer to non-constant user_struct so remove this unnecessary cast. Acked-by: Serge Hallyn <serge.hallyn@canonical.com> Signed-off-by: Eric W. Biederman <ebiederm@xmission.com>
