Subject: Fix misannotated out-of-line _copy_to_user()
Git-commit: a0e94598e6b6c0d1df6a5fa14eb7c767ca817a20
Patch-mainline: v4.16-rc1
References: bsc#1082625

Destination is a kernel pointer and source - a userland one
in _copy_from_user(); _copy_to_user() is the other way round.

Fixes: d597580d37377 ("generic ...copy_..._user primitives")
