Subject: [PATCH 3/3] arch/x86: make kernel/check.c explicitly non-modular

The Kconfig currently controlling compilation of this code is:

arch/x86/Kconfig:config X86_CHECK_BIOS_CORRUPTION
arch/x86/Kconfig:       bool "Check for low memory corruption"

...meaning that it currently is not being built as a module by anyone.

Lets remove the couple traces of modularity so that when reading the
code there is no doubt it is builtin-only.

Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.
