[PATCH] kernel/module: silence a gcc warning

[Mathieu Malaterre <malat@debian.org>]

In commit 8c8ef42aee8f ("module: include other structures in module version
check"), the function `struct_module` was renamed to `module_layout` but no
prototype was added to `include/linux/module.h`. Remove warning triggered
at W=1:

  kernel/module.c:4378:6: warning: no previous prototype for ‘module_layout’ [-Wmissing-prototypes]
