Arnd Bergmann 22ac37c530 nds32: fix access_ok() checks in get/put_user
commit 8926d88ced upstream.

The get_user()/put_user() functions are meant to check for
access_ok(), while the __get_user()/__put_user() functions
don't.

This broke in 4.19 for nds32, when it gained an extraneous
check in __get_user(), but lost the check it needs in
__put_user().

Fixes: 487913ab18 ("nds32: Extract the checking and getting pointer to a macro")
