From: Roman Stratiienko <roman.stratiie...@globallogic.com>
Since kernel v5.0 upstream commit 96d4f267e40f
("Remove 'type' argument from access_ok() function")
access_ok() funcion takes only 2 parameters
Change access_rok and access_wok wrappers for kernels
starting from v5.0, and preserve them for earlier versions
