x86/cpu/bugs: Make retpoline module warning conditional
(cherry picked from commit e383095c7fe8d218e00ec0f83e4b95ed4e627b02)
If sysfs is disabled and RETPOLINE not defined:
arch/x86/kernel/cpu/bugs.c:97:13: warning: ‘spectre_v2_bad_module’ defined but not used
[-Wunused-variable]
static bool spectre_v2_bad_module;
Hide it.
Fixes: caf7501a1b4e ("module/retpoline: Warn about missing retpoline in module")
