reboot: Fix build warning without CONFIG_SYSCTL
If CONFIG_SYSCTL is n, build warn: kernel/reboot.c:443:20: error: ‘kernel_reboot_sysctls_init’ defined but not used [-Werror=unused-function] static void __init kernel_reboot_sysctls_init(void) ^~~~~~~~~~~~~~~~~~~~~~~~~~ Move kernel_reboot_sysctls_init() to #ifdef block to fix this. Fixes: 06d177662fb8 ("kernel/reboot: move reboot sysctls to its own file") Signed-off-by: YueHaibing <yuehaibing@huawei.com> Signed-off-by: Luis Chamberlain <mcgrof@kernel.org>
