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

"Eric W. Beiderman

From: Eric W. Biederman <ebiederm@xmission.com>

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.
