MIPS: Loongson64: Fix build error 'secondary_kexec_args' undeclared u…

…nder !SMP On the Loongson64 platform, if CONFIG_SMP is not set, the following build error will occur: arch/mips/loongson64/reset.c:133:2: error:'secondary_kexec_args' undeclared Because the definition and declaration of secondary_kexec_args are in the CONFIG_SMP, the secondary_kexec_args variable should be used in CONFIG_SMP.
