MIPS: Loongson64: Fix build error 'secondary_kexec_args' undeclared under !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.
