[PATCH 04/43] userns: Remove unnecessary cast to struct user_struct when copying cred->user.

["\"Eric W. Beiderman" <ebiederm-aS9lmoZGLiVWk0Htik3J/w@public.gmane.org>]

From: Eric W. Biederman <ebiederm-aS9lmoZGLiVWk0Htik3J/w@public.gmane.org>

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.
