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")
