kfence, x86: only define helpers if !MODULE
x86's <asm/tlbflush.h> only declares non-module accessible functions
(such as flush_tlb_one_kernel) if !MODULE.
In preparation of including <asm/kfence.h> from the KFENCE test module,
only define the helpers if !MODULE to avoid breaking the build with
CONFIG_KFENCE_KUNIT_TEST=m.
