KNI calls `get_user_pages_remote()` API which is using `FOLL_TOUCH`
flag, but `FOLL_TOUCH` is no more in public headers since v6.3,
causing a build error.
`FOLL_*` defines in Linux kernel first moved to another header [1],
later some of them moved to memory subsystem internal header [2] for 6.3
`get_user_pages_remote()` already sets `FOLL_TOUCH` internally,
no need to set this flag externally anyway, moving flag from the call
altogether.
