[PATCH -next] modules: Fix up build when CONFIG_MODULE_UNLOAD=n.

[Paul Mundt <lethal@linux-sh.org>]

Commit 3d43321b7015387cfebbe26436d0e9d299162ea1 ("modules: sysctl to
block module loading") introduces a modules_disabled variable that is
only defined if CONFIG_MODULE_UNLOAD is enabled, despite being used in
other places. This moves it up and fixes up the build.

  CC      kernel/module.o
kernel/module.c: In function 'sys_init_module':
kernel/module.c:2401: error: 'modules_disabled' undeclared (first use in this function)
kernel/module.c:2401: error: (Each undeclared identifier is reported only once
kernel/module.c:2401: error: for each function it appears in.)
