Mel Gorman 496d2d2388 mm: security: Check early if HARDENED_USERCOPY is enabled 
HARDENED_USERCOPY is checked within a function so even if disabled, the
function overhead still exists. Move the static check inline.

This is at best a micro-optimisation and any difference in performance
was within noise but it is relatively consistent with the init_on_*
implementations.
