[PATCH] arm64: Remove the __user annotation for the restore_za_context() argument

[PATCH] arm64: Remove the __user annotation for the restore_za_context() argument

[Catalin Marinas]

The struct user_ctx *user pointer passed to restore_za_context() is not
a user point but a structure containing several __user pointers. Remove
the __user annotation.
