Origin: 352cdb28eecbb57de3509b18dfc37dcce0455c01
Author: ABC <abc@openwall.com>
Description: Fix compile for stable kernels by not using 'ref_module'
`ref_module' unexport in 7ef5264de7732 ("modules: mark ref_module
static") is back-ported into stable kernels making old `#if
LINUX_VERSION_CODE' checks irrelevant or too complicated to update.
Do not use `ref_module' API at all since `try_module_get' is ancient
enough to use always.
